redundancy_index: Redundancy index

In TImA97/randfindR: Analysis of Randomness in Human Generated Sequences

Redundancy index

Description

Computes index indicating the evenness of the response frequency distribution.

Usage

redundancy_index(x, options)

Arguments

x	vector of distinct options of numbers or characters
options	number of available options in sequence

Details

This function takes a vector x and weighs the observed information concerning the response frequencies against the highest observable information given the number of possible options. The resulting quotient is subtracted from 1 and then, multiplied with 100. A score of 0 indicates an even distribution of response frequencies, whereas a score of 100 indicates complete redundancy of one response.

Value

redundancy index of x
