What’s New in SAS/ETS 9.22

MDC Procedure

The following new features have been added to the MDC procedure:

  • The CLASS statement is now supported. A CLASS statement enables you to declare classification variables for use as explanatory effects in a model. When a CLASS variable is used as a predictor in the MODEL statement, the procedure automatically creates a dummy regressor that corresponds to each discrete value or level of the CLASS variable.

  • The MODEL statement now supports the use of CLASS variables and interaction terms as predictors.

  • The TEST statement is now supported to test linear equality restrictions on the parameters. Three tests are available: Wald, Lagrange multiplier, and likelihood ratio.
