WebLogistic regression is the statistical technique used to predict the relationship between predictors (our independent variables) and a predicted variable (the dependent variable) where the dependent variable is binary (e.g., sex , response , score , etc…). There must be two or more independent variables, or predictors, for a logistic regression.
