PROC LOGISTIC is invoked to fit the binary logit model to the grouped data. The ODDSRATIO statement computes odds ratios even though the main effects are involved in an interaction. Because Heat interacts with Soak, the odds ratio for Heat depend on the value of Soak. ODS Graphics is used ...
PROC HPLOGISTIC Features The HPLOGISTIC procedure estimates the parameters of a logistic regression model by using maximum likelihood techniques. It also does the following: provides model-building syntax with the CLASS and effect-based MODEL statements, which are familiar from SAS/STAT analytic ...

In particular, SAS PROC LOGISTIC may be used to fit a cumulative logits models whereby proportional odds is assumed for all explanatory variables by default (i.e., POM); it also provides a score test of the proportional odds assumption. Alternatively, a PPOM or NPOM can be fitted through ...
