问题如下:
If real estate investment adopts repeat sales index to measure return, what’s the most significant drawback?
选项:
A. Sample selection bias
B. Unreliable appraisal valuation
C. Underestimation of volatility
解释:
A is correct.
Repeat sales index 是基于实际成交统计,因为房产流动性较差,只会统计那些实际成交的样本,这样会产生样本选择偏差(Sample selection bias),所以A正确。
这道题可以解释下知识点吗感谢哦
