WebWe consider a flexible semiparametric approach, namely, partially linear single-index models, for ultra high-dimensional longitudinal data. Most importantly, we allow not only the partially linear covariates but also the single-index covariates within the unknown flexible function estimated nonparametrically to be ultra high dimensional. Web30 de jun. de 2024 · This paper studies group selection for high-dimensional partially linear model with the adaptive group bridge method. We also consider the choice of γ in the bridge penalty. It is worth mentioning that we use ‘leave-one-observation-out’ cross-validation to select both λ and γ.This method can significantly reduce the computational … Web1 de set. de 2013 · We generate data from the following additive partial linear model Y i = ∑ l = 1 d X i l α l + ∑ j = 1 p g j (Z i j) + ε i, i = 1, …, n with n being the sample size, d being … in the ketchup
