摘要: | 在線性回歸模式中,我們發展出三套Winsorized Means的理論: (1).Koenker and Bassett(1978) regression quantiles (2).Chen and Chiang(1996) symmetric quantile (3).Welsh(1987) residual quantile 在計算有效性的過程中,我們發現下面一些事實: (1).Winsorized Means不能改善Koenker and Bassett's and Welsh's Trimmed Means 的有效性. (2).Winsorized Means不但可以改善symmetric Trimmed Means, 而且它會更接近Cramer-Rao lower bound. |
