- The
MODEL statement now enables you to specify interaction terms among any of
the specified explanatory variables. Because of the more complicated models
that you can specify, you can only use a single MODEL statement in each PROC
PROBIT invocation.
- You can now graphically display results of model parameter estimation.
For binary data analysis, you can construct plots of predicted probabilities,
inverse predicted probabilities, and cumulative probabilities. For ordinal
multinomial models, you can display plots of predicted probabilities, linear
predictors, and cumulative probabilities. In addition, you can control graphical
features such as plot layout, colors, plotting symbols, line styles, and
the text fonts used in the plots.
- You can now include models that contain variables listed in the
CLASS statement and ordinal response multinomial models in the OUTEST= data
set.
