The jackknife method
The so-called jaekknife method has been introduced by Quenouille to reduce a bias in estimation and then progressively extended to obtain an estimate of variances. It is interesting in that it yields an improved estimator and enables the estimator to be assessed in an inexpensive way, that is with regard to the methodology although the computation, if required, is not necessarily inexpensive. By all standards the results thus obtained are impressive in most cases; but in a few, not very well defined, circumstances the results are either poor or ridiculous.
