null_score: Guttmann's Null-Score Quotient

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

Guttmann's Null-Score Quotient

Description

Guttmann's Null-Score Quotient

Usage

null_score(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 number of all response pairs that do not occur in this sequence given the number of possible options. The result of this computation is weighted with the highest possible number of unused response pairs for this sequence. The final result is attained by multiplying this quotient with 100. The result of this quotient ranges from 0 to 100. High scores indicate an uneven distribution of response pairs, whereas low scores indicate an even distribution of response pairs.

Value

Guttmann Null-Score Quotient of x
