New SAS Macros

MISS (version 1.05) uses the EM algorithm to estimate the parameters of a multivariate normal distribution when data are missing, and optionally generates multiply imputed data sets using the methods of J. L. Schafer, "Analysis of Incomplete Multivariate Data."  (Note:  Version 8 of SAS has PROC MI which accomplishes the same tasks, but is much faster).

COMBINE (version 1.03) takes  estimates based on multiply imputed data sets and combines them into a single set of estimates and associated statistics. (Note:  This macro has been superseded by PROC MIANALYZE which is available in version 8.1 of SAS).

COMBCHI (version 1.0) takes chi-square statistics from multiply imputed data sets and produces a single p-value.

GLOGIT does maximum likelihood estimation of logistic regression models for two or more groups when the residual variance is allowed to differ across groups.

LIFEHAZ  This is a new version of my LIFEHAZ macro which plots the hazard function for a model fitted by PROC LIFEREG. This version works for Release 6.12 through Release 8.2 of SAS.

PREDICT   This is a new version of my PREDICT macro which calculates survival probabilities for models fitted by PROC LIFEREG.  This version works for Release 8.2 of SAS, and may or may not work for earlier releases.

For other macros described in my books, check the Data section above.
