Perl module that calculates critical values of common statistical distributions

This Perl module calulates percentage points 5 significant digits of the u standard normal distribution, the student’s t distribution, the chi-square distribution and the F distribution. It can also calculate the upper probability 5 significant digits of the u standard normal, the chi-square, the t and the F distribution. These critical values are needed to perform statistical tests, like the u test, the t test, the F test and the chi-squared test, and to calculate confidence intervals.
