Ridge and Lasso regression are two methods for estimating the parameter vector of a linear regression model. They depend on a tuning parameter say A that controls the weight we give to the penalty compared to the residual sum of squares (RSS) in the cost function that is minimized Ridge Lasso of Bx to generate the parameter estimates B The parameter vector estimate satisfy For A→∞o we have Ridge Lasso → and B .
