Short Note on Ridge Regression

Introduction I am doing a couple of assignments involving penalized estimators such as Ridge regression, and I wanted to do a short derivation of its asymptotic covariance. In comparison to the existing resources which I could find, some details are left out, which I wanted to recapitulate more clearly. I’ll also contrast the variance of the Ridge estimator to the variance of the OLS estimator, illustrating a fact that also comes to the surface in many other resources, namely that the variance of the Ridge estimator is smaller than that of the OLS estimator.
