"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.
