多元线性回归及其速算技术

The Fast Calculation of Multivariate Linear Regression

回归分析的计算技术一般采用的方法是:一无线性回归分析多数用列表法;多无线性回归分析采用电子计算机程序进行运算。本文推荐一种电算器速算技术,对因素为四元及以下的线性回归分析,有便、快、省之功效。

The general method of the regressive calculation technique includes that for the single variable linear regressive analysis, the tabulated value is used & that for the mult ivariate regressive analysis, the computer programmed calculation is used, In this paper, a fast calculator technique is presented, When the factors are equal or smaller than 4, this linear regressive analysis has convenient, fast & economic effect.
