Quantile regression shrinkage and selection via the Lqsso

WebAbstract This study examines a penalized additive regression spline estimator with total variation and non negative garrote-type penalties. The proposed estimator is obtained based on a two-stage procedure. In the first stage, an initial estimator is obtained via total variation penalization. The total variation penalty enables data-adaptive knot selection … Web6 de abr. de 2024 · The resulting estimator is relatively easy to compute, ... the LARS algorithm and the non-negative garrotte are recently proposed regression methods that can be used to select individual variables. chrysler pt cruiser 2003ignition switch
