PHP Class MathPHP\Probability\Distribution\Table\TDistribution
Tables for one sided and two sided,
Initial index is degrees of freedom (ν).
Second index is confidence level precentage, or alpha value (α).

This table is provided only for completeness. It is common for statistics
textbooks to include this table, so this library does as well. It is better
to use the StudentT distribution functions when a t value is required.
