Online calculator. This online calculator calculates joint entropy of two discrete random variables given a joint distribution table (X, Y) ~ p.
 


Input

Input=0.5 0.25 0.25 0

Solution

Joint Entropy H(X,Y)=1.5000000000001

Joint Entropy Formula

JointEntropy=∑i=1∑i=1P(x,y)log2[P(x,y)] x and y are particular values of X and Y, respectively
P(x,y) is the joint probability of these values occurring together, and P(x,y)log2⁡[P(x,y)] is defined to be 0 if P(x,y)=01
