Bhattacharyya coefficient between two normal densities: the location modification

Description

Computes the Bhattacharyya coefficient (the mean-part) between two normal densities with means m1 and m0 and standard deviations sd1 and sd0

Usage

BC_normal_m1m0(m1, sd1, m0, sd0)

Arguments

m1

mean of the first normal density

sd1

standard deviation of the first normal density

m0

mean of the second normal density

sd0

standard deviation of the second normal density

Details

The function returns the mean-part of the BC under normal approximation according to Roos et al. (2020). The mean-part is adjusted for standard deviations which corresponds to the Mahalanobis distance. This part quantifies the location modification.

Value

A numeric value is returned.
