WebbWith logistic regression we model the natural log odds as a linear function of the explanatory variable: logit (y)=ln (odds)=ln =a + βχ (1) p ( 1 - p ) where p is the probability of interested outcome and x is the explanatory variable. The parameters of the logistic regression are α and β. This is the simple logistic model.

WebbLogistic regression aims to solve classification problems. It does this by predicting categorical outcomes, unlike linear regression that predicts a continuous outcome. In the simplest case there are two outcomes, which is called binomial, an example of which is predicting if a tumor is malignant or benign.
