shannon.entropy R Documentation
Calculate the Shannon entropy
Description
This function calculates the Shannon entropy for a discrete random variable
with finite n values sample.
Usage
shannon.entropy(p)
Arguments
p
A numeric object with non-negative values.
Details
The entropy is calculated by H(x) = -sum_i^n(P(x_i)log_b(P(x_i))).
Value
A numeric value of entropy is returned.
Author(s)
Ge Tan
Examples
x <- c(1, 1, 1, 1)
shannon.entropy(x)
x <- c(1, 0, 0, 0)
shannon.entropy(x)
