F-distribution functions

PDFF(x,df1,df2)

PDFF(x,df1,df2) returns the probability density at the value x of a F-distribution with degrees of freedom df1 and df2.

CDFF(x,df1,df2) returns the value at x of the F cumulative distribution with degrees of freedom df1 and df2.

RndF(df1,df2) returns a random value of a F distribution with degrees of freedom df1 and df2.
