Deviance Logistic Regression Distribution. Logistic Regression deals with the case where the dependent variable is binary and the conditional distribution is binomial. For example we could use logistic regression to model the relationship between various measurements of a manufactured specimen such as dimensions and chemical composition to predict if a crack greater than 10 mils will occur a binary variable.
Deviance is a number that measures the goodness of fit of a logistic regression model. Deviance is a likelihood ratio chi -square comparing the fitted model with a saturated model which can be obtained by allowing all possible interactions and non- linearities.
