Output Data Sets

OUTEST= SAS-data-set

The OUTEST= (or OUTVAR=) data set is of TYPE=EST and contains the final parameter estimates, the gradient, the Hessian, and boundary and linear constraints. For METHOD=ML, METHOD=GLS, and METHOD=WLS, the OUTEST= data set also contains the approximate standard errors, the information matrix (crossproduct Jacobian), and the approximate covariance matrix of the parameter estimates ((generalized) inverse of the information matrix). If there are linear or nonlinear equality or active inequality constraints at the solution, the OUTEST= data set also contains Lagrange multipliers, the projected Hessian matrix, and the Hessian matrix of the Lagrange function.

The OUTEST= data set can be used to save the results of an optimization by PROC TCALIS for another analysis with either PROC TCALIS or another SAS procedure. Saving results to an OUTEST= data set is advised for expensive applications that cannot be repeated without considerable effort.

The OUTEST= data set contains the BY variables, two character variables _TYPE_ and _NAME_, $\text{[math]}$ numeric variables corresponding to the parameters used in the model, a numeric variable _RHS_ (right-hand side) that is used for the right-hand-side value $\text{[math]}$ of a linear constraint or for the value $\text{[math]}$ of the objective function at the final point $\text{[math]}$ of the parameter space, and a numeric variable _ITER_ that is set to zero for initial values, set to the iteration number for the OUTITER output, and set to missing for the result output.

The _TYPE_ observations in Table 88.1 are available in the OUTEST= data set, depending on the request.

OUTMODEL= SAS-data-set

The OUTMODEL= (or OUTRAM=) data set is of TYPE=CALISMDL and contains the model specification and the computed parameter estimates and standard error estimates. This data set is intended to be reused as an INMODEL= data set to specify good initial values in a subsequent analysis by PROC TCALIS.

The OUTMODEL= data set contains the following variables:

the BY variables, if any
an _MDLNUM_ variable for model numbers, if used
a character variable _TYPE_, which takes various values indicating the type of model specification
a character variable _NAME_, which indicates the model type, parameter name, or variable name
a character variable _VAR1_, which is the name or number of the first variable in the specification
a character variable _VAR2_, which is the name or number of the second variable in the specification
a numerical variable _ESTIM_ for the final estimate of the parameter location
a numerical variable _STDERR_ for the standard error estimate of the parameter location

Each observation (record) of the OUTMODEL= data set contains a piece of information regarding the model specification. Depending on the type of the specification indicated by the value of the _TYPE_ variable, the meanings of _NAME_, _VAR1_, and _VAR2_ differ. The following tables summarize the meanings of the _NAME_, _VAR1_, and _VAR2_ variables for each value of the _TYPE_ variable, given the type of the model.

FACTOR Models

Value of _TYPE_	Specification Type	_NAME_	_VAR1_	_VAR2_
MDLTYPE	model type	model type
ADDPVAR	added (partial) variance	parameter	variable
COV	covariance	parameter	first variable	second variable
LOADING	factor loading	parameter	manifest variable	factor variable
MEAN	mean or intercept	parameter	variable
PVAR	(partial) variance	parameter	variable

For factor models, the value of the _NAME_ variable is either EFACTOR (exploratory factor model) or CFACTOR (confirmatory factor model) for the _TYPE_=MDLTYPE observation. Other observations specify the parameters in the model. The _NAME_ values for these observations are the parameter names. Any observation with a _TYPE_ value of COV or LOADING is for specifying a parameter associated with two variables. The _VAR1_ and _VAR2_ values of such an observation indicate the variables involved. Any observation with a _TYPE_ value of ADDPVAR, MEAN, or PVAR is for specifying a parameter associated with a single variable. The _VAR1_ value of such an observation indicates the variable involved, while the _VAR2_ value is not used.

LINEQS Models

Value of _TYPE_	Specification Type	_NAME_	_VAR1_	_VAR2_
MDLTYPE	model type	model type
ADDCOV	added covariance	parameter	first variable	second variable
ADDMEAN	added mean	parameter	variable
ADDSTD	added variance	parameter	variable
COV	covariance	parameter	first variable	second variable
EQUATION	path coefficient	parameter	outcome variable	predictor variable
MEAN	mean	parameter	variable
STD	variance	parameter	variable

The value of the _NAME_ variable is LINEQS for the _TYPE_=MDLTYPE observation. Other observations specify the parameters in the model. The _NAME_ values for these observations are the parameter names. Any observation with a _TYPE_ value of ADDCOV, COV, or EQUATION is for specifying a parameter associated with two variables. The _VAR1_ and _VAR2_ values of such an observation indicate the variables involved. Any observation with a _TYPE_ value of ADDMEAN, ADDSTD, MEAN, or STD is for specifying a parameter associated with a single variable. The _VAR1_ value of such an observation indicates the variables involved, while the _VAR2_ value is not used.

LISMOD Models

Value of _TYPE_	Specification Type	_NAME_	_VAR1_	_VAR2_
MDLTYPE	model type	model type
XVAR	x-variable	variable	variable number
YVAR	y-variable	variable	variable number
ETAVAR	eta-variable	variable	variable number
XIVAR	xi-variable	variable	variable number
ADDKAPPA	added _KAPPA_ entry	parameter	row number

THETAY	_THETAY_ entry	parameter	row number	column number

The value of the _NAME_ variable is LISMOD for the _TYPE_=MDLTYPE observation. Other observations specify either the variables or the parameters in the model.

Observations with _TYPE_ values equal to XVAR, YVAR, ETAVAR, and XIVAR indicate the variables on the respective lists in the model. The _NAME_ variable of these observations stores the names of the variables, while the _VAR1_ variable stores the variable numbers on the respective list. The variable numbers in this data set are not arbitrary—that is, they define the variable orders in the rows and columns of the LISMOD model matrices. The _VAR2_ variable of these observations is not used.

All other observations in this data set specify the parameters in the model. The _NAME_ values of these observations are the parameter names. The corresponding _VAR1_ and _VAR2_ values of these observations indicate the row and column locations of the parameters in the LISMOD model matrices specified in the _TYPE_ variable. For example, when the value of _TYPE_ is ADDPHI or PHI, the parameter specified is located in the _PHI_ matrix, with its row and column numbers indicated by the _VAR1_ and _VAR2_ values, respectively. Some observations for specifying parameters do not have values in the _VAR2_ variable. This means that the associated LISMOD matrices are vectors so that the column numbers are always 1 for these observations.

MSTRUCT Models

Value of _TYPE_	Specification Type	_NAME_	_VAR1_	_VAR2_
MDLTYPE	model type	model type
VAR	variable	variable	variable number
COVMAT	covariance	parameter	row number	column number
MEANVEC	mean	parameter	row number

The value of the _NAME_ variable is MSTRUCT for the _TYPE_=MDLTYPE observation. Other observations specify either the variables or the parameters in the model. Observations with _TYPE_ values equal to VAR indicate the variables in the model. The _NAME_ variable of these observations stores the names of the variables, while the _VAR1_ variable stores the variable numbers on the variable list. The variable numbers in this data set are not arbitrary—that is, they define the variable orders in the rows and columns of the mean and covariance matrices. The _VAR2_ variable of these observations is not used.

All other observations in this data set specify the parameters in the model. The _NAME_ values of these observations are the parameter names. The corresponding _VAR1_ and _VAR2_ values of these observations indicate the row and column locations of the parameters in the mean or covariance matrix, as specified in the _TYPE_ model. For example, when the value of _TYPE_ is COVMAT, the parameter specified is located in the covariance matrix, with its row and column numbers indicated by the _VAR1_ and _VAR2_ values, respectively. For observations with _TYPE_=MEANVEC, the _VAR2_ variable is not used because the column numbers are always 1 for parameters in the mean vector.

PATH Models

Value of _TYPE_	Specification Type	_NAME_	_VAR1_	_VAR2_
MDLTYPE	model type	model type
ADDPCOV	added (partial) covariance	parameter	first variable	second variable

LEFT	path coefficient	parameter	outcome variable	predictor variable
MEAN	mean	parameter	variable
PCOV	(partial) covariance	parameter	first variable	second variable
PVAR	(partial) variance	parameter	variable
RIGHT	path coefficient	parameter	predictor variable	outcome variable

The value of the _NAME_ variable is PATH for the _TYPE_=MDLTYPE observation. Other observations specify the parameters in the model. The _NAME_ values for these observations are the parameter names. Any observation with a _TYPE_ value of ADDPCOV, LEFT, PCOV, or RIGHT is for specifying a parameter associated with two variables. The _VAR1_ and _VAR2_ values of such an observation indicate the variables involved. Any observation with a _TYPE_ value of ADDMEAN, ADDPVAR, ADDSTD, MEAN, or PVAR is for specifying a parameter associated with a single variable. The _VAR1_ value of such an observation indicates the variable involved, while the _VAR2_ value is not used.

RAM Models

Value of _TYPE_	Specification Type	_NAME_	_VAR1_	_VAR2_
MDLTYPE	model type	model type
_A_	matrix _A_ entry	parameter	first variable	second variable
_P_	matrix _P_ entry	parameter	first variable	second variable

MEAN	mean	parameter	variable
PCOV	(partial) covariance	parameter	first variable	second variable
PVAR	(partial) variance	parameter	variable
RIGHT	path coefficient	parameter	predictor variable	outcome variable

The value of the _NAME_ variable is RAM for the _TYPE_=MDLTYPE observation. Other observations specify the parameters in the model. The _NAME_ values for these observations are for the parameter names. Any observation with a _TYPE_ value of _A_, _P_, ADDPCOV, LEFT, PCOV, or RIGHT is for specifying a parameter associated with two variables. The _VAR1_ and _VAR2_ values of such an observation indicate the variables involved. Any observation with a _TYPE_ value of _W_, ADDMEAN, ADDPVAR, INTERCEP, MEAN, or PVAR is for specifying a parameter associated with a single variable. The _VAR1_ value of such an observation indicates the variable involved, while the _VAR2_ value is not used.

Reading an OUTMODEL= Data Set As an INMODEL= Data Set in Subsequent Analyses

When the OUTMODEL= data set is treated as an INMODEL= data set in subsequent analyses, you need to pay attention to those observations with _TYPE_ values prefixed by "ADD" (for example, ADDCOV, ADDMEAN, or ADDSTD). These observations represent parameter locations added automatically by PROC TCALIS in a previous run. Because the context of the new analyses might be different, these observations for added parameter locations might not be suitable in the new runs any more. Hence, these observations are not read as input model information. Fortunately, after reading the INMODEL= specification in the new analyses, TCALIS analyzes the new model specification again. It then adds an appropriate set of parameters in the new context when necessary.

OUTSTAT= SAS-data-set

The OUTSTAT= data set is similar to the TYPE=COV, TYPE=UCOV, TYPE=CORR, or TYPE=UCORR data set produced by the CORR procedure. The OUTSTAT= data set contains the following variables:

the BY variables, if any
the _GPNUM_ variable for groups numbers, if used in the analysis
two character variables, _TYPE_ and _NAME_
the manifest and the latent variables analyzed

The OUTSTAT= data set contains the following information (when available) in the observations:

the mean and standard deviation
the skewness and kurtosis (if the DATA= data set is a raw data set and the KURTOSIS option is specified)
the number of observations
if the WEIGHT statement is used, sum of the weights
the correlation or covariance matrix to be analyzed
the predicted correlation or covariance matrix
the standardized or normalized residual correlation or covariance matrix
if the model contains latent variables, the predicted covariances between latent and manifest variables and the latent variable (or factor) score regression coefficients (see the PLATCOV option on )

In addition, for FACTOR models the OUTSTAT= data set contains:

the unrotated factor loadings, the error variances, and the matrix of factor correlations
the standardized factor loadings and factor correlations
the rotation matrix, rotated factor loadings, and factor correlations
standardized rotated factor loadings and factor correlations

If effects are analyzed, the OUTSTAT= data set also contains:

direct, indirect, and total effects and their standard error estimates
standardized direct, indirect, and total effects and their standard error estimates

Each observation in the OUTSTAT= data set contains some type of statistic as indicated by the _TYPE_ variable. The values of the _TYPE_ variable are shown in the following tables:

Basic Descriptive Statistics

Value of _TYPE_	Contents
CORR	correlations analyzed
COV	covariances analyzed
KURTOSIS	univariate kurtosis
MEAN	means
N	sample size
SKEWNESS	univariate skewness
STD	standard deviations
SUMWGT	sum of weights (if the WEIGHT statement is used)

For the _TYPE_=CORR or COV observations, the _NAME_ variable contains the name of the manifest variable that corresponds to each row for the covariance or correlation. For other observations, _NAME_ is blank.

Predicted Moments and Residuals

value of _TYPE_	Contents
METHOD=NONE
ASRES	asymptotically standardized residuals
NRES	normalized residuals

METHOD=WLS
WLSASRES	WLS asymptotically standardized residuals
WLSNRES	WLS normalized residuals
WLSPRED	WLS predicted moments
WLSRES	WLS raw residuals
WLSSRES	WLS variance standardized residuals

For residuals or predicted moments of means, the _NAME_ variable is a fixed value denoted by _Mean_. For residuals or predicted moments for covariances or correlations, the _NAME_ variable is used for names of variables.

Effects and Latent Variable Scores Regression Coefficients

Value of _TYPE_	Contents
Unstandardized Effects
DEFFECT	direct effects
DEFF_SE	standard error estimates for direct effects
IEFFECT	indirect effects
IEFF_SE	standard error estimates for indirect effects
TEFFECT	total effects
TEFF_SE	standard error estimates for total effects
Standardized Effects
SDEFF	standardized direct effects
SDEFF_SE	standard error estimates for standardized direct effects
SIEFF	standardized indirect effects
SIEFF_SE	standard error estimates for standardized indirect effects
STEFF	standardized total effects
STEFF_SE	standard error estimates for standardized total effects
Latent Variable Scores Coefficients
LSSCORE	latent variable (or factor) scores regression coefficients for ULS method
SCORE	latent variable (or factor) scores regression coefficients other than ULS method

For latent variable or factor scores coefficients, the _NAME_ variable contains factor or latent variables in the observations. For other observations, the _NAME_ variable contains manifest or latent variable names.

You can use the latent variable score regression coefficients with PROC SCORE to compute factor scores. If the analyzed matrix is a covariance rather than a correlation matrix, the _TYPE_=STD observation is not included in the OUTSTAT= data set. In this case, the standard deviations can be obtained from the diagonal elements of the covariance matrix. Dropping the _TYPE_=STD observation prevents PROC SCORE from standardizing the observations before computing the factor scores.

Factor Analysis Results

Value of _TYPE_	Contents
ERRVAR	error variances
FCORR	factor correlations or covariances
LOADINGS	unrotated factor loadings
RFCORR	rotated factor correlations or covariances
RLOADING	rotated factor loadings
ROTMAT	rotation matrix
STDFCORR	standardized factor correlations
STDLOAD	standardized factor loadings
STDRFCOR	standardized rotated factor correlations or covariances
STDRLOAD	standardized rotated factor loadings

For the _TYPE_=ERRVAR observation, the _NAME_ variable is blank. For all other observations, the _NAME_ variable contains factor names.

OUTWGT= SAS-data-set

You can create an OUTWGT= data set that is of TYPE=WEIGHT and contains the weight matrix used in generalized, weighted, or diagonally weighted least squares estimation. The OUTWGT= data set contains the weight matrix on which the WRIDGE= and the WPENALTY= options are applied. However, if you input the inverse of the weight matrix with the INWGT= and INWGTINV options (or the INWGT(INV)= option alone) in the same analysis, the OUTWGT= data set contains the same elements of the inverse of the weight matrix. For unweighted least squares or maximum likelihood estimation, no OUTWGT= data set can be written. The weight matrix used in maximum likelihood estimation is dynamically updated during optimization. When the ML solution converges, the final weight matrix is the same as the predicted covariance or correlation matrix, which is included in the OUTSTAT= data set (observations with _TYPE_ =MAXPRED).

For generalized and diagonally weighted least squares estimation, the weight matrices $\text{[math]}$ of the OUTWGT= data set contain all elements $\text{[math]}$ , where the indices $\text{[math]}$ and $\text{[math]}$ correspond to all manifest variables used in the analysis. Let $\text{[math]}$ be the name of the $\text{[math]}$ th variable in the analysis. In this case, the OUTWGT= data set contains $\text{[math]}$ observations with the variables shown in the following table:

Variable	Contents
_TYPE_	WEIGHT (character)
_NAME_	name of variable $\text{[math]}$ (character)
$\text{[math]}$	weight $\text{[math]}$ for variable $\text{[math]}$ (numeric)
$\text{[math]}$	$\text{[math]}$
$\text{[math]}$	weight $\text{[math]}$ for variable $\text{[math]}$ (numeric)

For weighted least squares estimation, the weight matrix $\text{[math]}$ of the OUTWGT= data set contains only the nonredundant elements $\text{[math]}$ . In this case, the OUTWGT= data set contains $\text{[math]}$ observations with the variables shown in the following table:

Variable	Contents
_TYPE_	WEIGHT (character)
_NAME_	name of variable $\text{[math]}$ (character)
_NAM2_	name of variable $\text{[math]}$ (character)
_NAM3_	name of variable $\text{[math]}$ (character)
$\text{[math]}$	weight $\text{[math]}$ for variable $\text{[math]}$ (numeric)
$\text{[math]}$	$\text{[math]}$
$\text{[math]}$	weight $\text{[math]}$ for variable $\text{[math]}$ (numeric)

Symmetric redundant elements are set to missing values.

OUTFIT= SAS-data-set

You can create an OUTFIT= data set that is of TYPE=CALISFIT and contains the values of the fit indices of your analysis. If you use two estimation methods such as LSML or LSWLS, the fit indices are for the second analysis. An OUTFIT=data set contains the following variables:

a character variable _TYPE_ for the types of fit indices
a character variable _INDEX_ for the names of the fit indices
a numerical variable _VALUE_ for the numerical values of the fit indices
a character variable _PRINT_ for the character-formatted fit index values.

The possible values of _TYPE_ are:

Incremental:: fit indices that are based on comparison with a baseline model
