- InverseTDistribution[ <Degrees of Freedom>, <Probability> ]
- Computes the inverse of cumulative distribution function of t-distribution at p, where the t-distribution has d degrees of freedom. In other words, finds r such that P(X≤r)=p, where X is random variable with t-distribution. Probability p must be from [0,1].
