多系列相关系数的矩法估计
The Matric Estimation of Multiple-series Relevant Coefficient
【摘要】 通过对正态的名义变量的等级量化,用矩估计法给出了一个计算多系列相关系数的一般公式。使由Jaspan给出的公式成为特例,并给出了当等级量化成等差数列时的计算公式。
【Abstract】 The present paper presents a general formula of calculating multiple-series relevant coefficient with the method of matric estimation through evaluation of the nominal variables.This conclusion makes the formula given by Jaspan just be a special case,and it also presents a calculation formula when the evaluation of nominal variables is an arithmetical progression.
