Functions

double gammln (double xx)
 Calculates natural log of a gamma function.
double gammq (double a, double x)
 Calculates Q, the probability that the chi2 should exceed a particilar chi2 (input) by chance.
void gcf (double *gammcf, double a, double x, double *gln)
 Calculates Q, the probability that the chi2 should exceed a particilar chi2 (input) by chance, by using continued fractions.
void gser (double *gamser, double a, double x, double *gln)
 Calculates Q, the probability that the chi2 should exceed a particilar chi2 (input) by chance, by using series approximation.
