least square analysis meaning in Chinese

最小平方分析

Firstly , we estimate the variance and the mean of each cell with maximum likelihood ; secondly , we identify the important dispersion effects based on least squares analysis of the logarithm of within - replication variance ; last , we identify the important location effects based on weighted least squares analysis of the mean of each cell . a simulation study also demonstrates its superiority over some existing methods . an experiment for the robust design of thermostat is used to illustrate the method
本文对带有右截尾数据的有重复因子试验，提出了另一种分析位置效应和散度效应的方法：首先，在每一个试验点，对重复试验观察值用极大似然法估计出均值和方差；其次，用每个试验点方差估计值的对数作为响应变量与各因子建立回归模型，鉴别出显著的散度效应；之后，采用加权最小二乘法鉴别出比较显著的位置效应。
