The TCALIS Procedure

FITINDEX Statement
FITINDEX option <option ...> ;

You can use the FITINDEX statement to set the options for computing and displaying the fit indices, or to output the fit indices. All but the OFF= and ON= options of the FITINDEX statement are also available in the PROC TCALIS statement. The options set in the FITINDEX statement will overwrite those set in the PROC TCALIS statement.

For the listing of fit indices and their definitions, see the section Overall Model Fit Indices. Note that not all fit indices are available with all estimation methods, which is specified by the METHOD= option of the PROC TCALIS statement. See the section Fit Indices and Estimation Methods for more details.

The options of the FITINDEX statement are as follows:

ALPHAECV=

specifies a confidence interval () for the Browne and Cudeck (1993) expected cross validation index (ECVI). See the ALPHAECV= option of the PROC TCALIS statement.

ALPHARMS=

specifies a confidence interval () for the Steiger and Lind (1980) root mean square error of approximation (RMSEA) coefficient. See the ALPHARMS= option of the PROC TCALIS statement.

CHICORRECT | CHICORR = name  |  c

specifies a correction factor for the chi-square statistics for model fit. See the CHICORRECT= option of the PROC TCALIS statement.

CLOSEFIT=p

defines the criterion value p for indicating a close fit. See the CLOSEFIT= option of the PROC TCALIS statement.

DFREDUCE=i

reduces the degrees of freedom of the test by . See the DFREDUCE= option of the PROC TCALIS statement.

NOADJDF

turns off the automatic adjustment of degrees of freedom when there are active constraints in the analysis. See the NOADJDF option of the PROC TCALIS statement.

NOINDEXTYPE

disables the display of index types in the fit summary table. See the NOINDEXTYPE option of the PROC TCALIS statement.

OFF | OFFLIST= [names]  |  {names}

turns off the printing of one or more fit indices or modeling information as indicated by names, where a name represents a fit index, a group of fit indices, or modeling information. Names must be specified inside a pair of parentheses and separated by spaces. By default, all fit indices are printed. See the ON= option for the value of names.

ON | ONLIST < (ONLY) > = [names]  |  {names}

turns on the printing of one or more fit indices or modeling information as indicated by names, where a name represents a fit index, a group of fit indices, or modeling information. Names must be specified inside a pair of parentheses and separated by spaces. Because all fit indices and modeling information are printed by default, using an ON= list alone is redundant. When both ON= and OFF= lists are specified, the ON= list will override the OFF= list for those fit indices or modeling information that appear on both lists. If an ON(ONLY)= list is used, only those fit indices or modeling information specified in the list will be printed. Effectively, an ON(ONLY)= list is the same as the specification with an ON= list with the same selections and an OFF=ALL list in the FITINDEX statement.

Output Control of Fit Index Groups and Modeling Information Group
