Instead of leaving out one observation at a time, we leave out *d* observations. Therefore, the size of a delete-*d* jackknife sample is (*n* - *d*), and there are jackknife samples.

Let denote applied to the data set with subset *s* removed. The formula for the delete-*d* jackknife estimate of s.e. is

It can be shown that the delete-*d* jackknife is consistent for the median if and . Roughly speaking, it is preferrable to choose a *d* such that for the delete-*d* jackknife estimation of standard error.
