CLASS Statement

The LIFEREG Procedure

CLASS Statement

CLASS variables ;

Variables that are classification variables rather than quantitative numeric variables must be listed in the CLASS statement. For each explanatory variable listed in the CLASS statement, indicator variables are generated for the levels assumed by the CLASS variable. If you use a CLASS statement, you cannot output parameter estimates to the OUTEST= data set (you can output them to a data set via ODS). If the CLASS statement is used, it must appear before any of the MODEL statements.
