Computing the noncentrality parameter of the noncentral F distribution

Description

Returns the noncentrality parameter of the noncentral F ditribution if probability of Type I and Type II error, degrees of freedom of the numerator and the denominator in the F test statistics are given. It may be useful for computing minimal detectable differences. 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. http://dx.doi.org/10.1007/s11222-008-9061-3 Preprint of this paper is available at http://reliablecomputing.eu/ncbeta.html

Usage

ncparam(type1, type2, nu1, nu2)

Arguments

type1 Probability of Type I error
type2 Probability of Type II error
nu1 Degrees of freedom of the numerator in the F test statistics
nu2 Degrees of freedom of the denominator in the F test statistics
