upsilon.gof.statistic: Upsilon Goodness-of-Fit Test Statistic

In Upsilon: Another Test of Association for Count Data

Upsilon Goodness-of-Fit Test Statistic

Description

(FOR INTERNAL USE ONLY) Calculates the Upsilon statistic for a Goodness-of-Fit (GoF) test.

Usage

upsilon.gof.statistic(x, p = rep(1/length(x), length(x)), rescale.p = TRUE)

Arguments

x	a numeric vector or one-column matrix representing observed counts.
p	a numeric vector of probabilities of the same length as x. Defaults to a uniform distribution (1/length(x)).
rescale.p	a logical scalar. If TRUE (default), p is rescaled to sum to 1. If FALSE, and p does not sum to 1, an error is raised.

Details

This statistic measures the discrepancy between observed counts and expected probabilities.

Value

A numeric value of the Upsilon Goodness-of-Fit statistic.

Examples

library("Upsilon")
counts <- c(10, 20, 30)
upsilon.gof.statistic(counts)
