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.
