The MODEL statement defines the statistical model in terms of a response variable (the target) or an events/trials specification, model effects constructed from variables in the input data set, and options. An intercept is included in the model by default. You can remove the intercept with the NOINT option.
You can specify a single response variable that contains your binary, ordinal, or nominal response values. When you have binomial data, you can specify the events/trials form of the response, where one variable contains the number of positive responses (or events) and another variable contains the number of trials. Note that the values of both events and (trials – events) must be nonnegative and the value of trials must be positive.
For information about constructing the model effects, see the section Specification and Parameterization of Model Effects of Chapter 4: Shared Statistical Concepts.
There are two sets of options in the MODEL statement. The responseoptions determine how the HPLOGISTIC procedure models probabilities for binary data. The modeloptions control other aspects of model formation and inference. Table 9.3 summarizes these options.

Response variable options determine how the HPLOGISTIC procedure models probabilities for binary and multinomial data.
You can specify the following responseoptions by enclosing them in parentheses after the response or trials variable.
