**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macro has been superseded by PROC MIANALYZE which is available in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.
