这题考察的是遗漏变量对回归模型的影响，

因为回归模型遗漏了重要变量，因此这个模型都是错误的，所以它将不满足模型必须的假设条件，模型参数本身也是错误的。

NO.PZ2015120204000018 问题如下 If omittevariable is correlatewith variables alrea incluin the mol, coefficient estimates will biaseaninconsistent anstanrerrors will also inconsistent. Is this Statement correct? A.Yes. B.No, because the mol’s coefficient estimates will unbiase C.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. 遗漏变量带来的结果不是异方差和自相关么？这两个问题都是不影响系数的啊？而且老师课上也说遗漏变量主要是影响残差项，和系数有什么关系？

NO.PZ2015120204000018 有问必答里之前有位助教的是影响了b1的估计就会导致inconsistent。但是多重共线性中会影响b1的估计也不会影响inconsistent，所以为什么ommitex会导致呢
