entropy_2 R Documentation
Computes the entropy between two variables
Description
It calculates the entropy between two categorical variables using log2.
This log2 is mentioned in most of the Claude Shannon bibliography.
Input/target can be numeric or character.
Usage
entropy_2(input, target)
Arguments
input
numeric/character vector
target
numeric/character vector
Value
Entropy measured in bits
Examples
## Not run:
# Measuring entropy between input and target variable
entropy_2(input=data_golf$outlook, target=data_golf$play_golf)
## End(Not run)
