F Distribution


- degrees of freedom #1 (positive integer)
- degrees of freedom #2 (positive integer)


Probability Density Function

Cumulative Distribution Function

where is the Beta Function,  and is the Regularized Incomplete Beta Function.


Since this distribution is rarely used for modelling applications, it is provided for reference only, and cannot be fitted to data.
