`scipy.stats._qmc:_perturb_discrepancy`

source: build-install/usr/lib/python3.14/site-packages/scipy/stats/_qmc.py:522

Signature

def _perturb_discrepancy(sample: np.ndarray, i1: int, i2: int, k: int, disc: float)

Summary

Centered discrepancy after an elementary perturbation of a LHS.

Extended Summary

An elementary perturbation consists of an exchange of coordinates between two points: sample[i1, k] <-> sample[i2, k]. By construction, this operation conserves the LHS properties.

Parameters

sample : array_like (n, d): The sample (before permutation) to compute the discrepancy from.
i1 : int: The first line of the elementary permutation.
i2 : int: The second line of the elementary permutation.
k : int: The column of the elementary permutation.
disc : float: Centered discrepancy of the design before permutation.

Returns

discrepancy : float: Centered discrepancy of the design after permutation.
