优势分析方法及其应用

Dominance Analysis and Its Application

优势分析是近年来由Budescu等人新发展起来的一种确定多元回归方程中各预测变量相对重要性的方法。与传统方法相比,优势分析突出的特点是,全面比较了在由全模型所衍生出来的所有子模型情况下,各预测变量(X1,X…XP)在解释或预测标准变量у时,它们之间的相对重要性。本文从基本原理以及具体操作过程对这一新的统计分析方法进行了详细介绍。

Dominance analysis is the newly proposed method that determines the relative importance of predictive variables in multiple regression. Its impressive advantage over traditional methods was that dominance analysis compares the relative importance of the predictors in regression equation in all possible situations. The article introduceds dominance analysis in terms of its principles and computational process.
