Math::CDF 0.1

Math::CDF is a Perl module to generate probabilities and quantiles from several statistical probability functions.

SYNOPSIS

use Math::CDF;

$prob = &Math::CDF::pnorm(1.96);

if( not defined($z = &Math::CDF::qnorm(0.975)) ) { die "qnorm() failed"; }

or

use Math::CDF qw(:all);

$prob = pnorm(1.96);

This module provides a perl interface to the DCDFLIB. See the section on DCDFLIB for more information.

Functions are available for 7 continuous distributions (Beta, Chi-square, F, Gamma, Normal, Poisson and T-distribution) and for two discrete distributions (Binomial and Negative Binomial). Optional non-centrality parameters are available for the Chi-square, F and T-distributions. Cumulative probabilities are available for all 9 distributions and quantile functions are available for the 7 continuous distributions.

All cumulative probability function names begin with the character "p". They give the probability of being less than or equal to the given value [ P(X
