Compute the JeffriesMatusita distance between two probability distributions.
1 2  ## S4 method for signature 'Distribution,Distribution'
JeffriesMatusita(p1, p2)

p1, p2 

Let p1
and p2
denote 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
JeffriesMatusita distance between p1
and p2
is given by
sqrt(2 * (1  Fidelity(p1, p2)))
.
The JeffriesMatusita distance may also be expressed in terms of any of the following: Euclidean distance, Bhattacharya distance 2, and Hellinger metric. It is straightforward to arrive at any of these expressions.
The JeffriesMatusita distance between distributions p1
and
p2
