Web5.3.4 The Bootstrap¶. We illustrate the use of the bootstrap in the simple example of Section 5.2, as well as on an example involving estimating the accuracy of the linear regression model on the Autodata set.. Estimating the Accuracy of a Statistic of Interest¶ Webridgecv = RidgeCV(alphas = alphas, scoring = 'neg_mean_squared_error', normalize = True) ridgecv.fit(X_train, y_train) ridgecv.alpha_ Therefore, we see that the value of alpha that results in the smallest cross-validation error is 0.57. What is the test MSE associated with this value of alpha?
