遗漏的变量是如何影响consistency和系数呢？烦请老师解答，谢谢🙏
Yes,because omittevariable biwill only affethe estimates of regression coefficients. Yes, because the effeof the omittevariable biis the same the sericorrelation. A is correct. Because both the coefficient estimates anthe consistenwill affecteunr the omittevariable bias. 请问是如何影响consisten的呀，还不是很明白，consisten是说n越大越精确，那在有遗漏变量的情况下难道n越大就越不精确？
