Performs jackknife resampling on numpy arrays.

Jackknife resampling is a technique to generate ‘n’ deterministic samples of size ‘n-1’ from a measured sample of size ‘n’. Basically, the i-th sample, (1<=i<=n), is generated by means of removing the i-th measurement of the original sample. Like the bootstrap resampling, this statistical technique finds applications in estimating variance, bias, and confidence intervals.

data : numpy.ndarray

Original sample (1-D array) from which the jackknife resamples will be generated.

resamples : numpy.ndarray

The i-th row is the i-th jackknife sample, i.e., the original sample with the i-th measurement deleted.
