Summary:Categorical responses are very common in biotechnology research. In this paper we present the main ideas of generalized linear models, with particular emphasis to logit models. We apply these models to two practical situations. The first problem studies the effect of chilling on bud development in azalea flowers, and the second situation analyzes the relationship between a genetic polymorphism in certain protein and obesity in humans. Both problems are analyzed with SAS PROC CATMOD.
