These functions give you access to the hypergeometric distribution. For more information about Fathom's distribution functions, click here.
hyperGeomProbability(c, N, S, n) hyperGeomCumulative(c, N, S, n) hyperGeomQuantile(c, N, S, n) N = population size |
The probability, cumulative, and quantile functions for the hypergeometric distribution. This is the distribution of number of successes in a sample of size n when you draw without replacement from a population of size N which has S successes in it. |
You may also draw random values from this distribution:
randomHyperGeom(N, S, n) |
A random value drawn from that distribution. |
This illustration compares the hypergeometric to the related binomial distribution (in which we sample with replacement).
