The main conclusion is as follows: traditional method imputed missing data is easy, but it cann't express the uncertainty of the missing value. Furthermore, it increases the sampling error and distorts the distribution, ect.
本文主要的結(jié)論有:1.缺失數(shù)據(jù)的傳統(tǒng)估算方法雖簡單易行，但山於未考慮缺失值的不確定性、加大抽樣誤差、扭曲樣本分佈等，無法真實(shí)地反映研究事物的特征。
