摘要: 自动逐步回归方法在于自动地选入重要的自变量到回归方程中,使其估计精度一般来说达到最优,其计算机程序在一般微型计算机上可处理80个自变量(样本容量不限)的实际问题。

Abstract: The method of stepwise Iinear regression is to establish the RELATION between a dependent variable and some important independent variables. y=a+b1x1+b2x2+……+bLxL The method of auto stepwise in this paper lies in automa tically selecting important independet variables so that the ESTIMATE ACCURACY reaches the best level in general. The program was written in BASIC on PC-1500.
