| Author: | Ali Baharev [aut, cre] |
| Maintainer: | Ali Baharev <ali.baharev@gmail.com> |
| 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. |

Computing the noncentrality parameter of the noncentral F distribution
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 in the F test statistics are given.
Usage
ncparamF(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 |
Value
The noncentrality parameter is returned.
Examples
result <- ncparamF(0.05, 0.10, 2, 10)
stopifnot(all.equal(result, 17.43876, tolerance = 1e-5))
