Detailed Description

Test if data from a given distribution using Bhattacharyya overlap.

Uses builder() to build a pdf from supplied data. This is then tested against the target distribution using an estimate of the Bhattacharyya overlap.

	)		`[virtual, inherited]`

Test whether data came from the given distribution, using bootstrap.

Repeatedly resamples n values from data[0..n-1] and compares with the given pdf. Individual comparisons are returned in B.

Returns:: Mean of B
