Euclidean(p1, p2)

Arguments

p1, p2

Distributions.

Details

Let p1 and p2 denote the vectors of probability mass assigned by two distributions defined on the same state space. Then, the Euclidean distance between p1 and p2 is given by (sum(abs(p1 - p2)^2))^(1/2).

The Euclidean distance is equal to the 2-metric.

Value

The Euclidean distance between distributions p1 and p2.
