double studtv(double p, double v);
Returns the critical point of the Student's T random variable distribution function with degrees of freedom v associated with probability p.
Parameters:
p | Cummulative probability for the critical point. |
---|---|
v | Degrees of freedom. |
Returns:
x such that P(X ≤ x | v) = p
Errors:
NUMERICS_ERROR
is raised if v ≤ 0, p ≤ 0, or p ≥
Usage:
double x = studtv(.5, 1.5)
