chisq.conf: Confidence Functions for Pearson's Chi-squared Parameter

In ddarmon/clp: R Package for Computing Confidence Functions to Accompany CLP

Description

Confidence functions for Pearson's chi-squared parameter for an I x J contingency table using the profile likelihood.

Usage

chisq.conf(N, plot = TRUE, conf.level = 0.95)

Arguments

N	an I x J matrix of counts
plot	whether to plot the confidence density and curve
conf.level	the confidence level for the confidence interval indicated on the confidence curve

Value

A list containing the confidence functions pconf, dconf, cconf, and qconf for Pearson's chi-squared parameter, as well as the P-curve and S-curve.
