Bias of an estimator – Wikipedia – In statistics, the bias (or bias function) of an estimator is the difference between this estimator’s expected value and the true value of the parameter being estimated.
One of the central goals of data analysis is an estimate of the uncertainties in fit parameters. Sometimes standard methods for getting these errors are unavailable.
In statistics, the jackknife is a resampling technique especially useful for variance and bias estimation. The jackknife predates other common resampling.

This article explains the jackknife method for estimating bias and standard errors. It gives two examples and shows how to implement the jackknife in SAS.
For many statistical parameters the jackknife estimate of variance tends asymptotically to the true. "Nonparametric estimates of standard error: The jackknife,

Vincent, have you (or has anyone else) written jackknife regression into an R package as of yet? It would seem a useful tool in the arsenal, and while it’s not hard.
The Jackknife Estimation Method – was inspired by the previous success of the Jackknife procedure.1. Imagine. Mathematical Statistics, that the Jackknife estimate of the standard error is roughly.
