WebThe LOGISTIC procedure is similar in use to the other regression procedures in the SAS System. To demonstrate the similarity, suppose the response variable y is binary or ordinal, and x1 and x2 are two explanatory variables of interest. To ﬁt a logistic regression model, you can use a MODEL statement similar to that used in the REG procedure:

WebLogistic regression predicts the probability of the dependent response, rather than the value of the response (as in simple linear regression). In this example, the dependent variable is frequency of sex (less than once per month versus more than once per month). In this case, we are predicting having sex more than once per month.
