The t-values Calculator is a new Minerazzi tool, available now at

http://www.minerazzi.com/tools/t-values/calculator.php

The tool works by computing, through numerical approximation methods, the Inverse Cumulative Distribution Function or ICDF (also known as the Quantile Function, QF) of the Student’s t Distribution.

This new tool complements our p-values Calculator, described in

and available at

The t-values calculator comes handy when you don’t have around statistical t-tables or want to t-testing at confidence levels and degrees of freedom not listed in such tables. In fact, with a small change to the script, we can build another tool for the generation of t-tables at any confidence level and degrees of freedom as specified by a user.

Both tools will eventually be used to provide a third tool: The t-p Transformation tool that, as the name suggests, transforms CDF (t-to-p) into ICDF (p-to-t) results and vice versa.
