Compute the noncentral F-distribution's cumulative distribution function (CDF), given an F-value, the numerator and denominator degrees of freedom, and the noncentrality parameter. The noncentral F-distribution is one of the foundational statistical distributions used in analytics.

Compute the cumulative distribution function (CDF) for the noncentral t-distribution, given a t-value, the value of the noncentrality parameter, and the degrees of freedom. The noncentral t-distribution CDF yields the area under the noncentral t-distribution from negative infinity to t, which is very useful for analytics-related tasks such as computing statistical power and robust data modeling.

Compute the probability density function (PDF) for the noncentral t-distribution, given the degrees of freedom, the value of the noncentrality parameter, and a t-value. The noncentral t-distribution PDF identifies the relative likelihood that an associated random variable will have a particular value, and is very useful for analytics studies that incorporate noncentral t-distribution probabilities.
