In statistics, the logistic model ( or logit model) is a widely used statistical model that, in its basic form, uses a logistic function to model a binary dependent variable; many more complex extensions exist. In regression analysis, logistic regression ( or logit regression) is estimating the parameters of a logistic model; it is a form of binomial statistical modeling, regression analysis is a set of statistical processes for estimating the relationships among variables.

It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables ( or ' predictors' ).
