NO.PZ2015120204000017 问题如下 Contionheteroskesticity will result in consistent coefficient estimates, but both the t-statistianF-statistic will biase resulting in false inferences. Is this Statement correct? A.Yes. B.No, because the mol’s F-statistic will not biase C.No, because the mol’s t-statistiwill not biase A is correct.Chang is correbecause the presenof contionheteroskesticity results in consistent parameter estimates, but biase(up or wn) stanrerrors, t-statistics, anF-statistics. 老师，此题的条件异方差对系数的估计和一致性不是没影响么？怎么理解题目里的英文？
前半句Contionheteroskesticity will result in consistent coefficient estimates怎么理解呢？不是说条件异方差不会影响参数估计的一致性吗？那为什么前半句说的相反的呢？
问下讲义上的相关内容，请问下为啥有type 2 eerror,有条件异方差，每个error term之间有联系，只会减少stanrerror，怎么SE会too large?
