Calculates the probability densities, cumulative probabilities, and inverse cumulative probabilities for an F distribution.
The F distribution is a sampling distribution of two independent random variables with chi-square distributions, each divided by its degrees of freedom. It is most commonly used in test of variance. Use when random variables are greater than 0.
