Parameters

k size_t

value to evaluate LPMF (e.g. number of correct draws of object of interest)

N size_t

total population size

K size_t

number of relevant objects in population

n size_t

number of draws

Examples

import mir.math.common: log;
import mir.test: shouldApprox;

0.hypergeometricLPMF(7, 4, 3).shouldApprox == log(0.02857143);
1.hypergeometricLPMF(7, 4, 3).shouldApprox == log(0.3428571);
2.hypergeometricLPMF(7, 4, 3).shouldApprox == log(0.5142857);
3.hypergeometricLPMF(7, 4, 3).shouldApprox == log(0.1142857);
