cluster_ratio: Cluster ratio index

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

Cluster ratio index

Description

compute the population variance of all response pair frequencies

Usage

cluster_ratio(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 all response pair frequencies given the number of possible options. A score of 0 indicates no variance among response pair frequencies, i.e., all response pairs occur equally often. An example of this is the sequence '1-1-2-2' (response pairs: '1-1', '1-2', '2-2', and '2-1' from the last to the first value) as each response pair occurs exactly once. Higher scores indicate an increased degree of variance in the distribution of response pair frequencies.

Value

cluster ratio of x
