SpletLogistic regression is a statistical analysis method used to predict a data value based on prior observations of a data set. A logistic regression model predicts a dependent data variable by analyzing the relationship between one or more existing independent variables. SpletLogistic Regression.

Splet13. nov. 2024 · Advantages of Logistic Regression 1. Logistic Regression performs well when the dataset is linearly separable. 2. Logistic regression is less prone to over-fitting but it can overfit in high dimensional datasets. You should consider Regularization (L1 and L2) techniques to avoid over-fitting in these scenarios.
