Inverse Of The Cumulative Distribution For T-Statistic
 Syntax `ittail(`p`, `free`)` See Also ttail , tpdf , ftail

Description
Computes the element-by-element inverse of the cumulative distribution for the T-statistic, where p is a real or double-precision matrix specifying the value of the tail probability. Each of the elements of p must be greater than 0 and less than 1. The matrix free specifies the number of degrees of freedom for the T-statistic and may be integer, real, or double-precision. If t is the return value, ```           +infinity          /      p = | tpdf(x, free) dx          /           t ```where tpdf is the probability density function for the T-statistic.

Example
If you enter ```      p = [.1, .5, .9]      free = 3      ittail(p, free) ``` O-Matrix will respond ```      [ 1.63768 , 0 , -1.63768 ] ```
