Some users might be unfamiliar with updates made in the previous releases. SAS/STAT 13.1 introduced the BCHOICE, ICLIFETEST, and IRT procedures. Following are highlights of the other enhancements in SAS/STAT 13.1:
The MI procedure added the MNAR statement to facilitate sensitivity analysis.
The Tweedie distribution is supported by the GENMOD procedure.
The competing-risks model of Fine and Gray (1999) is available in the PHREG procedure.
The NLIN procedure enables you to generate both bootstrap estimates of confidence intervals for the parameters and bootstrap estimates of the covariance matrix and correlation matrix of the parameter estimates.
The MCMC procedure is multithreaded.
Path diagrams are available in the CALIS procedure.
You can compute power for PROC GLM–type MANOVA and repeated measurements in the GLMPOWER procedure.
The SURVEYMEANS procedure produces domain quantile estimates.
