The dependent/response variable is binary or dichotomous. The first assumption of logistic regression is that response variables can only take on two possible outcomes – pass/fail, male/female, and malignant/benign. This assumption can be checked by simply counting the unique outcomes of the dependent variable.

Witryna31 mar 2024 · Logistic regression is a supervised machine learning algorithm mainly used for classification tasks where the goal is to predict the probability that an instance of belonging to a given class or not. It is a kind of statistical algorithm, which analyze the relationship between a set of independent variables and the dependent binary variables.
