Bias Correction with Jackknife, Bootstrap, and Taylor Series

Abstract

We analyze bias correction methods using jackknife, bootstrap, and Taylor series. We focus on the binomial model, and consider the problem of bias correction for estimating f(p)f(p), where fC[0,1]f \in C[0,1] is arbitrary. We characterize the supremum norm of the bias of general jackknife and bootstrap estimators for any continuous functions, and demonstrate the in delete-dd jackknife, different values of dd may lead to drastically different behaviors in jackknife. We show that in the binomial model, iterating the bootstrap bias correction infinitely many times may lead to divergence of bias and variance, and demonstrate that the bias properties of the bootstrap bias corrected estimator after r1r-1 rounds are of the same order as that of the rr-jackknife estimator if a bounded coefficients condition is satisfied.
