Deviance Logistic Regression Distribution. The smaller the deviance the closer the fitted value is to the saturated model. Logistic regression models a relationship between predictor variables and a categorical response variable.

Deviance residual is another type of residual measures.

Logistic regression helps us estimate a probability of falling into a certain level of the categorical response given a set of predictors.
