问题如下图:
选项:
A.
B.
C.
解释:
这里的correlated依然是指一般或低度相关吧
NO.PZ201512020300000306 为什么这里parameter estimates 是 inconsistent. 样本容量没变,难道不是不影响consistency吗
NO.PZ201512020300000306 老师 这个知识点在哪
NO.PZ201512020300000306 No, because the mol’s coefficient estimates will unbiase No, because the mol’s coefficient estimates will consistent. A is correct. Chang is correbecause a correlateomittevariable will result in biaseaninconsistent parameter estimates aninconsistent stanrerrors. 一致性为什么会Bias
No, because the mol’s coefficient estimates will unbiase No, because the mol’s coefficient estimates will consistent. A is correct. Chang is correbecause a correlateomittevariable will result in biaseaninconsistent parameter estimates aninconsistent stanrerrors. 为什么?遗漏的变量和在mol内的变量相关被删除了还会bias?还有什么强弱相关性?完全不知道是哪里的知识点
No, because the mol’s coefficient estimates will unbiase No, because the mol’s coefficient estimates will consistent. A is correct. Chang is correbecause a correlateomittevariable will result in biaseaninconsistent parameter estimates aninconsistent stanrerrors. 这个题不是说遗漏变量吧?不是说省略的变量与现存其他变量是correlate吗?那不是应该省略,怎么会带来一系列问题呢?
