The Wald test is used to perform a joint test of the null hypotheses specified in a single TEST statement, where is the vector of intercept and slope parameters. When you should specify a CONTRAST statement instead.. Each equation specifies a linear hypothesis … WitrynaLogistic regression enables you to investigate the relationship between a categorical outcome and a set of explanatory variables. The outcome, or response, can be dichotomous (yes, no) or ordinal (low, medium, high). When you have a dichotomous response, you are performing standard logistic regression.
