pchisqGC: Graphical Calculator for Chi-Square Probabilities

Description Usage Arguments Value Author(s) Examples

View source: R/pchisqGC.R

Description

Shades desired areas under a specified chi-square curve, returns numerical value of the area.

Usage

1
pchisqGC(bound,region="above",df=NA,xlab="chi_square_statistic",graph=FALSE)

Arguments

bound

A numerical vector of length 1, indicating boundary of shaded region on horizontal axis

region

A character string. Possible values are "below" and "above"

df

Degrees of freedom of the chi-square distribution

xlab

Label for the horizontal axis

graph

produce graph?

Value

Numerical value of area under curve over region. Also plots the chi-square curve with the shaded area.

#This gives P(X < 6.8) where X is chisq with 3 degrees of freedom:
pchisqGC(6.8,df=3,region="below")

#This gives P(X >= 6.8), where X is chisq with 3 degrees of freedom
pchisqGC(6.8,df=3,region="above")

The 'mosaic' package masks several functions from core packages in order to add 
additional features.  The original behavior of these functions should not be affected by this.

Note: If you use the Matrix package, be sure to load it BEFORE loading mosaic.
