老师看看我的回答写得怎么样～

NO.PZ2020012102000007 问题如下 scrithe main issues tharise when concting historicanalysis of reestate returns. Properties tra infrequently so there is no ta on simultaneous perioc transaction prices for a selection of properties. Analysis therefore relies on appraisals. Secony, eaproperty is fferent, it is saito heterogenous. The returns calculatefrom appraisals represent weighteaverages of unobservable returns. Publishereturn series is too smooth anthe sample volatility unrstates the true volatility of returns. It also storts estimates of correlations. 解析:房地产交易不频繁，因此没有选择房地产的同时定期交易价格的数据。因此，分析依赖于评价。其次，每个属性都是不同的，它被称为异质的。从估价中计算出的收益是不可观察到的收益的加权平均数。公布的收益序列过于平滑，样本波动率低估了收益的真实波动率。它还扭曲了对相关性的估计。 这个主观题是重点需要背的吗

So we might neeto use appraistUsing Appraista coulunrestimate the correlation anvolatility.
