Calling Sequence

quantile_f (q,m,n)

Description

Returns the q-quantile of a F random variable F(m,n), with m,n>0; in other words, this is the inverse of cdf_f. Argument q must be an element of [0,1].

This function has no closed form and it is numerically computed if the global variable numer equals true, otherwise it returns a nominal expression.
