ww_test: Wald-Wolfowitz Runs Tests for Randomness

In traversc/trqwe: Performance oriented statistical metrics and utility functions.

Description

This is the k-category asymptotic Z Test with continuity correction. Imagine rolling a die multiple times to obtain a sequence of rolls. This statistic tests whether there exists a "run" within the sequence where one particular number comes up more times in a row than expected randomly. If the test is significant, it can be concluded that the die rolls are not independent.

Usage

ww_test(x)

Arguments

x	A vector of items, coerced into a factor.

Value

A p-value for the statistical test.
