We consider a simple logistic regression with a dichotomous exposure (E) and a single dichotomous confounder (Z), but the model and results obtained below can easily be expanded to include multiple categorical or continuous confounders.

Note that diagnostics done for logistic regression are similar to those done for probit regression. Half Normal Plot. fitted.values Logistic regression is used to predict the class (or category) of individuals based on one or multiple predictor variables (x). Why is using regression, or logistic regression "better" than doing bivariate analysis such as Chi-square? I read a lot of studies in my graduate school studies, and it seems like half of the studies use Chi-Square to test for association between variables, and the other half, who just seem to be trying to be fancy, conduct some complicated regression-adjusted for-controlled by- model.
