- 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
LIFEREG invocation.
- The new PROBPLOT statement enables you to construct probability
plots for complete or censored data. You can display the fitted distribution
and confidence intervals along with nonparametric estimates of the CDF on
the probability plots. In addition, you can control graphical features such
as plot layout, colors, plotting symbols, line styles, and the text fonts
used in the probability plot.
- You can now include models that contain variables listed in the
CLASS statement in the OUTEST= data set.
- You can now obtain standardized and Cox-Snell residuals in the
OUTPUT= data set.
