计算机的发展与普及,推动了多元统计分析在医学上(包括多元正常值同题)的应用。现就估计多元正常值的几种方法简介如下:1.多元线性回归法对多元线性资料确定正常值时,常用逐步回归法求得多元线性回归方程(?)=b_0+b_1x_1+…b_px_p(1)及剩余标准差 S_((?).1,2,)…P_。式中(?)为回归值(Y 表示作为应变量的观察因素),b_j(j=1,2,P)为回归系 The development and popularization of computers has promoted the application of multivariate statistical analysis in medicine (including multivariate normal values). Several methods for estimating multivariate normal values ​​are summarized as follows: 1. Multiple linear regression method When multivariate linear data is used to determine normal values, a multivariate linear regression equation (?)=b_0+b_1x_1+...b_px_p(1) is usually obtained by a stepwise regression method. And the remaining standard deviation S_((?).1,2,)...P_. Where (?) is the regression value (Y represents the observed variable as a dependent variable) and b_j(j=1, 2, P) is the regression
