Why ? it is highly possible that because explanatory variables are highly correlated , the resulted large standard errors could indicate an parameter to be insignificant while it is indeed significant 为什么?解释变量很可能高度相关,即使变量实际上显著,结果中的较大的标准差也可能表明参数不显著。
By taking repetitive observations in this paper , parametric estimators are obtained respectively in a simple structural ev linear model and a linear structural ev model with vector explanatory variables 本文利用重复抽样的方法,分别给出了简单线性结构型ev模型和一般线性结构型ev模型中的参数估计,并讨论了估计的强相合性与渐近正态性。
