NAME
Test::Probability - test if results are distributed correctly
SYNOPSIS
use Test::Probability;
my @results;
for (0 .. 1000) {
$results[rand_fn()]++;
}
my @probabilities = (0.5, 0.2, 0.3);
my $confidence = 0.9;
dist_ok(@results, @probabilities, $confidence,
"results match expected with confidence $confidence");
DESCRIPTION
Does your random-number generating function output the distribution you expect? Now you can find out! This module performs a chi-squared test at the specified confidence interval.
EXPORTS
- dist_ok
-
dist_ok(@results, @probabilities, $confidence, "results match probabilities with confidence $confidence");
