PHP 클래스 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). https://en.wikipedia.org/wiki/Student%27s_t-distribution#Table_of_selected_values 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.
