%description
Returns the noncentrality parameter of the noncentral F distribution if
probability of type I and type II error, degrees of freedom of the
numerator and the denominator are given.  It may be useful for computing
minimal detectable differences for general ANOVA models.  This program is
documented in the paper of A. Baharev, S. Kemeny, On the computation of
the noncentral F and noncentral beta distribution; Statistics and
Computing, 2008, 18 (3), 333-340.
