English Abstract the SAS procedure CATMOD fits linear models to
functions of categorical data. By choosing appropriate response functions
well known statistical procedures such as linear regression, anova, repeated
measures, log-linear models and logistic regression are available. Still
more can be done by using user-defined response functions (for instance
proportional hazard models). The estimating methodes used by CATMOD are
empirical generalized least squares (EGLS) and maximum likelihood
(ML).
