Bhattacharya2(p1, p2)

p1, p2 

Let p1
and p2
denote the vectors of probability mass assigned
by two distributions defined on the same state space. Let rho(p1, p2)
denote the fidelity similarity between p1
and p2
. Then, the
Bhattacharya distance 1 between p1
and p2
is given by
acos(rho(p1, p2))^2
; the Bhattacharya distance 2 between p1
and p2
is given by log(rho(p1, p2))
.
A Bhattacharya distance between distributions p1
and p2
