ncstudtv

double ncstudtv(double p, double v, double delta);

Returns the critical point of the Non-central Student's T random variable distribution function with degrees of freedom v and non-centrality parameter delta associated with probability p.

Parameters:
pCummulative probability for the critical point.
vDegrees of freedom.
deltaNon-centrality parameter

Returns:
x such that P(X ≤ x | v, delta) = p

Errors:
NUMERICS_ERROR is raised if v ≤ 0, delta < 0, p ≤ 0, or p ≥ 1

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