InvXX_Dist
Advanced Analysis Library Only
AnalysisLibErrType InvXX_Dist (double probabilityOfXx, int degreesOfFreedom, double *xx);
Purpose
Calculates xx, given a probability (0 ≤ p < 1), such that:
prob(
< x) = p
where is a random variable from a chi-square distribution with the specified degrees of freedom.
 |
Note When probabilityOfXx = 0, xx = 0. |
Example Code
double p, x;
n;
p = 0.635;
n = 2;
InvXX_Dist (p, n, &x);
