var_digits: Variance of digits

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

Variance of digits

Description

Computes the variance of marginal totals

Usage

var_digits(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 computes the population variance of response frequencies given the number of possible options. A score of 0 indicates an even distribution of response frequencies. Higher scores indicate an increasing redundancy of one or several responses. This index is conceptually closely related to the idea of the redundancy_index.

Value

variance of digits of x
