gives the cumulative probability beyond x for Student's distribution with df degrees of freedom.
- To use , you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
- The one-sided ‐value is CDF[StudentTDistribution[df],teststat] for , and 1-CDF[StudentTDistribution[df],teststat] for .
- The two-sided ‐value is twice the one-sided ‐value.
- The following option can be given:
TwoSided False whether to perform a two-sided test
