【摘要】 刀切法是从母样本的几个子样本中的每个子样本,得出所感兴趣的参数的估计值,然后通过子样本估计值间的变异来估计母样本估计量的方差.将刀切法应用在Warner模型中,并估计了πAW的方差.更多还原

【Abstract】 According to the theory of Jackknife,the parameter estimate is derived from each subsample of several subsamples of the mother sample,and then the variance of estimator of mother sample is evaluated through the variation of subsamples’ estimates.Herein,Jackknife was applied to Warner Model and the variance of AW was estimated.更多还原
