WebHere is some code to compute the non-negative garrote estimator with ridge regression as an initial estimator, and compare it with ridge regression without the additional garrote shrinkage. # Setting the parameters p <-100 n <-500 n.test <-5000 sparsity <-0.2 rho <-0.5 SNR <-3 set.seed(0) ... WebSimilar to other methods of regularization, the non- negative garrote estimation procedure proceeds in two steps once the initial estimate is chosen. First the so- lution pathd(‚) indexed by the tuning parameter‚ is constructed. The second step, oftentimes referred to as tuning, selects the ﬂnal estimate on the solution path.
