source
Bevington, pages 192-193.
purpose
evaluate probability for exceeding chi square
usage
result = pchisq (chisqr, nfree)
description of parameters
chisqr - comparison value of reduced chi square
nfree - number of degrees of freedom
subroutines and function subprograms required
gamma (x)
calculates gamma function for integers and 1/2-integers
comments
