requests that all variables in the input table are treated as ID variables when a scoring table is produced. In other words, if this option is specified, all variables from the input table, including computed columns, are transferred to the scoring table.

specifies a number between 0 and 1 from which to determine the confidence level for approximate confidence intervals of the parameter estimates. The default is α = 0.05, which leads to 100 x (1- α)% = 95% confidence limits for the parameter estimates.

specifies to add confidence intervals to the table of parameter estimates. The confidence level is 100*(1-α)% where α is determined by the ALPHA= option. The default value is α = 0.05. This value is equivalent to a 95% confidence limit.

specifies the formats for the classification variables in the model. If you do not specify the CLASSFORMATS= option, the default format is applied for the classification variable. That default format was determined when the table was originally loaded into the server. In the following example, the CLASSFORMAT= values apply to variables x1 and x2.

logistic y (x1 x2) = x3-x7 / classformats=("YN.", "F8.");

requests that the server produce SAS scoring code based on the actions that it performed during the analysis. The server generates DATA step code. By default, the code is replayed as an ODS table by the procedure as part of the output of the statement. More frequently, you might want to write the scoring code to an external file by specifying options.

specifies to model the largest ordered value for the dependent variable instead of the smallest. This option is useful for modeling responses with the value of 1 instead of modeling for value 0.

specifies the result tables that you want to exclude from being generated on the server and from being sent to the SAS session. The GLM statement can generate the following tables:

specifies the formats for the GROUPBY variables. If you do not specify the FORMATS= option, or if you omit the entry for a GROUPBY variable, the default format is applied for that variable.

proc imstat data=lasr1.table1;
   statement / groupby=(a b) formats=("8.3", "$10");
quit;

specifies a relative function convergence criterion. For all techniques except NMSIMP, termination requires a small relative change of the function value in successive iterations. Suppose that Ψ is the p × 1 vector of parameter estimates in the optimization, and the objective function at the kth iteration is denoted as f(Ψ)^k. Then, the FCONV criterion is met if

specifies the numeric variable that provides frequencies for the analysis. For example, if the FREQ= variable has the value 5, then it implies that the record represents five such observations with identical values for the modeling variables. If you specify a FREQ= variable, then only the observations with a value that is not missing and greater than zero for the variable are used in the analysis.

specifies a relative gradient convergence criterion. For all optimization techniques except CONGRA and NMSIMP, termination requires that the normalized predicted function reduction is small. The default value is r = 1e-8. Suppose that Ψ is the p × 1 vector of parameter estimates in the optimization with ith element Ψ_i. The objective function, its p × 1 gradient vector, and its p × p Hessian matrix are denoted, f(Ψ), g(Ψ), and H(Ψ ), respectively. Then, if superscripts denote the iteration count, the normalized predicted function reduction at iteration k is

specifies the names of the Group-by variables in the order of the grouping hierarchy. If no variable names are specified, the model is fit across the entire table—possibly subject to a WHERE clause.

specifies a section of the group-by hierarchy to be included in the computation. With this option, you can request that the server performs the analysis for only a subset of all possible groupings. The subset is determined by applying the group filter to a temporary table that you generate with the GROUPBY statement.

proc imstat;
    table example.cars_program_all;
    groupby state city trade_in_model / temptable 
                 weight=new_vehicle_msrp 
                 agg   =(max) 
                 order =weight;  
run;

    table example.cars_program_all;
    distinct sales_type / groupfilter=(
                 table  =mylasr.&_TEMPLAST_
                 scoregt=40000
                 valuelt=("FL","Ft Myers","")
                 limit  =20
                 descending);
run;

specifies the variables from the active table to transfer to the temporary table that is created by scoring the input table. This option has no effect unless the SCORE option is also specified. (See the SCORE option for details about which variables are added to the temporary table by default.) The IDVARS= option should be used to transfer additional columns from the input table to the scoring table.

requests to add details about the iterative model fitting process (an iteration history) to the ODS output tables.

requests that the results for a partitioned analysis are displayed in the order of the partition keys. If this option is not specified, then results are displayed by using the partitions on the first worker node followed by the partitions on the second node, and so on. Without this option, the results are likely to have random ordering of the partitions. The KEYORDER option makes result collection less efficient but produces a natural, predictable order.

specifies the link function to use for the model fitting process. See the following list for the available functions:

specifies the maximum number n of function calls in the iterative model fitting process. The default value depends on the optimization technique as follows:

specifies the maximum number of iterations in the iterative model fitting process. The default value depends on the optimization technique as follows:

specifies the maximum number of levels in an effect for which the server generates Type III tests. The idea behind the MAXTESTLEV= option is that testing effects for significance that have a large number of levels is typically not meaningful. The effects tend to be highly significant anyway, but determining the exact significance level is computationally intensive. The default value is 300 and implies that no test statistics are produced for any effect that has more than 300 levels.

specifies the name to use for identifying the model in the server output and in the temporary table of results generated by the TEMPTABLE option. SAS name rules apply. For example, the following statements add the 'Model' entry to the ModelInformation table.

proc imstat;
   table hps.neuralgia;
   logistic pain = treatment sex duration / name = LogisModel
run;

specifies the number of levels for each classification variables to show in the Class Level Information ODS table. If you do not specify the NOCLPRINT option, all unique values are shown in the order of the class variable levelization. If you specify NOCLPRINT=n, then the values are shown for those classification variables that have less than n levels only. The value for n must be at least 1.

For example, the following Class Level Information table is displayed with NOCLPRINT=4. Because the number of levels for variable Smoking_Status exceeds 4, the values are not displayed.

suppresses the inclusion of an intercept in the model. By default, all models contain an intercept term.

prevents the procedure from preparsing and pregenerating code for temporary expressions, scoring programs, and other user-written SAS statements.

prevents the computation of the covariance matrix and the standard errors of the parameter estimates. When you specify this option, the Type III tests for the model effects are also not available.

specifies the offset variable for the analysis. An offset variable can be thought of as a regressor variable whose regression coefficient is known to be 1. Offsets are used to shift the linear predictors by a certain amount. For example, an offset can be used to accommodate constants in the underlying model. For example, a model for the probability of being seropositive is as follows:

When you specify this option and the table is partitioned, the results are calculated separately for each value of the partition key. In other words, the partition variables function as automatic GROUPBY variables. This mode of executing calculations by partition is more efficient than using the GROUPBY= option. With a partitioned table, the server takes advantage of knowing that observations for a partition cannot be located on more than one worker node.

statement / partition="F          11"; /* passed directly to the server */
statement / partition="F","11";        /* composed by the procedure */

specifies a variable in the in-memory table that defines whether an observation belongs to the training set, the validation set, or is to be excluded from the analysis. The role variable can have a numeric or character type, and it can be a temporary computed variable.

requests that the active table be scored after the model is fit and the results be stored in a temporary table. The server automatically adds all model variables to the temporary table with the score results. These results include the response variable, the class variables, all explanatory variables from which effects are formed, and the WEIGHT=, and FREQ= variables.

specifies the list of ODS tables that you want to display for the analysis. The specified list replaces the default tables that are generated by the server and displayed. See the EXCLUDE= option for the list of default tables and the table names that you can display.

requests that the server perform variable selection for the model. A backward selection method is used, where the significance level for an effect to remain in the model is determined by the SLSTAY= option. This option performs variable selection like the VARSEL option, but in contrast to the latter option, it displays output only for the selected effects.

specifies the significance level used in determining whether effects should stay in the model during variable selection.

specifies the optimization technique.

specifies either a quoted string that contains the SAS expression that defines the temporary variables or a file reference to an external file with the SAS statements.

specifies the list of temporary variables for the request. Each temporary variable must be defined through SAS statements that you supply with the TEMPEXPRESS= option.

generates an in-memory temporary table from the result set. The IMSTAT procedure displays the name of the table and stores it in the &_TEMPLAST_ macro variable, provided that the statement executed successfully.

specifies the proportion f in the validation data set.

specifies that the server perform variable selection for the model. A backward selection method is used, where the significance level for an effect to remain in the model is determined by the SLSTAY= option. In contrast to the SHOWSEL option, all effects are reported in the IMSTAT output.

specifies the numeric variable to use as a weighing variable in solving the linear model.
