Abstract
Logistic regression is widely used in analysis of categorical data especially data with variables that have binary responses. It can be used in many fields where discrete responses and a set of explanatory variables coexist. For instance, it can be used in survival analysis which often uses data with variable having values of ‘success ’ and ‘failure’. We can let logistic regression do more things for us by extending it. This paper will discuss under what circumstances we extend logistic regression by using SAS.
