Variance Estimation for the Second-Order Jackknife
二阶刀切法的方差估计
This paper considers Sharot's family of jackknives (1976) and chooses a member of it using a minimum variance based criterion. The criterion is different from that considered by Sharot, which is claimed to be inappropriate. Results on the variance estimator of the jackknife are derived and compared with those of Hinkley (1978). A Monte Carlo simulation study supports the above conclusion.
