Some users might be unfamiliar with updates that were made in the previous release. SAS/STAT 13.2 introduced the GEE, ICPHREG, and SPP procedures. Following are highlights of the other enhancements in SAS/STAT 13.2:
The FACTOR procedure generates path diagrams.
The FMM procedure fits multinomial models.
The FREQ procedure provides score confidence limits for the odds ratio and the relative risk.
The GLMSELECT procedure enables you to apply safe screening and sure independence screening methods to reduce a large number of regressors to a smaller subset on which model selection is performed.
The IRT procedure generates polychoric correlation matrices, item characteristic curves, and test information curve plots.
The LOGISTIC procedure enables you to add or relax constraints on parameters in nominal response and partial proportional odds models.
The MCMC procedure supports a categorical distribution in the MODEL, RANDOM, and PRIOR statements.
The NLMIXED procedure enables you to specify more than one RANDOM statement in order to fit hierarchical nonlinear mixed models.
The SEQDESIGN procedure enables you to create a ceiling-adjusted design that corresponds to integer-valued sample sizes at the stages for nonsurvival data.
