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.
