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. WebIt does this through the use of odds and logarithms. So, the logit is a nonlinear function that represents the s-shaped curve. Let’s look more closely at how this works. [‘Generalized linear models’ refers to a class of models that uses a link function to make estimation possible.
