Logistic regression is an extension of “regular” linear regression. It is used when the dependent variable, Y, is categorical. We now introduce binary logistic regression, in which the Y variable is a “Yes/No” type variable. We will typically refer to the two categories of Y as “1” and “0,” so that they are ...
