WebQuantile regression is a method of natural regression analysis which uses the central trend and the degree of statistical distribution to obtain a more comprehensive and powerful analysis. In this talk, we propose a weighted composite quantile regression (WCQR) estimation approach and study model selection for high dimensional nonlinear models. Web29 de ago. de 2024 · We propose forward variable selection procedures with a stopping rule for feature screening in ultra-high-dimensional quantile regression models. For such very large models, penalized methods do not work and some preliminary feature screening is …
