For the Students data file, model y = whether you are a vegetarian, with the 13 other explanatory variables used in Section 11.5.3. For ordinary logistic regression, show that this model fits better than the null model, but no Wald tests are significant. Use the lasso, with λ to minimize the sample mean prediction error in crossvalidation and with the one-standard-error rule. Compare estimates to those from ordinary logistic regression.
