In probability theory and statistics, the noncentral F-distribution is a continuous probability distribution that is a generalization of the (ordinary) F-distribution.
Implementations
The noncentral F-distribution is implemented in the R programming language (e.g., pf function), in MATLAB (ncfcdf, ncfinv, ncfpdf, ncfrnd and ncfstat functions in the statistics toolbox) and in Mathematica (NoncentralFRatioDistribution function).
