(15 points) Let be the solution you obtain in standard least-squares linear regression, and Bridge be the solution you obtain in ridge regression. (a) If you scale all the input features (but not the response y) by a factor of c before fitting the regression, what is the new estimator of model coefficient as a function of ? (b) If you scale all the input features (but not the response y) by a factor of c before fitting the ridge regression, what is the new estimator of model coefficient as a function of Bridge?
