Let’s load the necessary packages. Logistic regression assumes: 1) The outcome is dichotomous; 2) There is a linear relationship between the logit of the outcome and each continuous predictor variable; 3) There are no influential cases/outliers; 4) There is no multicollinearity among the predictors. ” The closer the AUC is to 1, the better the model. 1. .
