The Best Screen Analysis of Small Sample Multivariate Gradation Regression in Statistical Research

摘要

Gradation regression analysis generally needs adequate samples from which we can obtain more reliable statistical results. However, in some statistical analysis, owing to some practical difficulties, we cannot obtain satisfactory observation numbers of indexes. Therefore, this article makes use of screen method of gradation regression by stages and in batches and deals with this kind of problem successfully.
