fratiov

double fratiov(double p, double v1, double v2);

Returns the critical point of the F-ratio random variable distribution function with v1 degrees of freedom numerator and v2 degrees of freedom denomenator associatied with probability p.

Parameters:
pCummulative probability for the critical point.
v1Numerator degrees of freedom.
v2Denominator degrees of freedom.

Returns:
x such that P(X ≤ x | v1, v2) = p

Errors:
NUMERICS_ERROR is raised if v1 ≤ 0, v2 ≤ 0, p ≤ 0, or p ≥

Usage:
double x = fratiov(.5, 1.5, 2.75)
