Probabilities.HypGeometricCDFInv Function

Hypergeometric distribution point percent function (PPF).

Pascal

function HypGeometricCDFInv(p: double; M: Integer; K: Integer; N: Integer): double; overload;

Parameters	Description
p	Probability, real positive value on closed interval [0,1].
M	Defines total number of elements, valid values ae integers on closed interval [0,X].
K	Defines number of elements with certain traits, valid values are integers on closed interval [X,M].
N	Defines number of samples, valid values are integers on closed interval [X,M].

Returns

the hypergeometric distribution point percent function (PPF) for probability p using the integer parameters M (total number of elements), K (number of elements with a certain trait) and N (number of samples drawn).

Description

function HypGeometricCDFs(x: Integer; M, K, N: Integer): single; overload;

The result is the least integer such that the hypergeometric CDF evaluated at result equals or exceeds p.
