WebFeb 11, 2024 · In logistic regression, the dependent variable is a binary variable that contains data coded as 1 (yes, success, etc.) or 0 (no, failure, etc.). In other words, the logistic regression model predicts P (Y=1) as a function of X. Independent variables can be categorical or continuous, for example, gender, age, income, geographical region and …

The primary difference between linear regression and logistic regression is that logistic regression's range is bounded between 0 and 1.
WebThe logistic regression model is an example of a broad class of models known as generalized linear models (GLM).
