WebRidge regression is a technique which is used for analyzing multiple regression where the data suffers from multicollinearity. The problem which arises due to multicollinearity is that the basic linear regression model (least square estimates) becomes unbiased and the variance becomes so large that the predicted values are far from the true value. WebJan 12, 2024 · Here, the implementation for Bayesian Ridge Regression is given below. The mathematical expression on which Bayesian Ridge Regression works is : where alpha is the shape parameter for the Gamma distribution prior to the alpha parameter and lambda is the shape parameter for the Gamma distribution prior to the Lambda parameter.
