Webb28 okt. 2024 · Logistic regression is a method we can use to fit a regression model when the response variable is binary. Logistic regression uses a method known as maximum likelihood estimation to find an equation of the following form: log [p (X) / (1-p (X))] = β0 + β1X1 + β2X2 + … + βpXp. where: Xj: The jth predictor variable.
