scripts default iconEntropy Calculator (Scripts) Publisher's description

Calculates entropy for data (probability of events) in an array.

Calculates entropy for data (probability of events) in an array.
In information theory, entropy is a measure of the uncertainty associated
with a random variable. In this context, the term usually refers to the
Shannon entropy, which quantifies the expected value of the information
% contained in a message, usually in units such as bits. In this context, a
'message' means a specific realization of the random variable.
Shannon denoted the entropy H of a discrete random variable X with possible
values {x1, ..., xn} as,

H(X) = E(I(X)).

E is the expected value,
I is the information content of X

Example usage
in = [.25 .25 .25 .25];
b = 'bit';
Entropy = info_entropy (in, b)
