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. |
