• dF(x, d1, d2)—Returns the probability density for value x.

• pF(x, d1, d2)—Returns the cumulative probability distribution for value x.

• qF(p, d1, d2)—Returns the inverse cumulative probability distribution for probability p.

• rF(m, d1, d2)—Returns a vector of m random numbers having the F-distribution.

Arguments

• x is a scalar or vector of real values, x ≥ 0. To allow integration and other operations over this argument, values outside of the stated range are allowed, but they produce a 0 result.

• d1, d2 are positive integers representing the degrees of freedom. While the distribution equation is meant to be formulated for integers, you can also use real values.

• p is a real probability, 0 ≤ p ≤ 1.

• m is an integer, m > 0.
