bhattacharyya.prob(gM,gS, cM,cS, alpha=1)

bhattacharyya.dist(gM, gS, cM, cS)

bhattacharyya.coeff(gM,gS, cM,cS, alpha=1)

Arguments

gM, cM

P-dimensional vector of cluster means

gS, cS

PxP-dimensinal matrix of clusters co-variances

alpha

A value between 0 and 1 used to balance the bhattacharrya probabilities, coefficients calculated with either the full covariance matrices or using only the diagonal elements of it.

Details

Calculates the bhattacharyya probabilty, distance or coefficient of the clusters, i.e. Gaussian distributions. Distance and Coefficient are symetric for both clusters, whereas the probabity is not.

Value

The Bhattacharyya probability, distance or coefficient
