stats_dens_pmf_hypergeometric
(PECL stats >= 1.0.0)
stats_dens_pmf_hypergeometric — Probability mass function of the hypergeometric distribution
Description
stats_dens_pmf_hypergeometric(
float
float
float
float
): float
float
$n1,float
$n2,float
$N1,float
$N2): float
Returns the probability mass at n1, where the random variable
follows the hypergeometric distribution of which the number of failure is
n2, the number of success samples is N1,
and the number of failure samples is N2.
Parameters
-
n1 -
The number of success, at which the probability mass is calculated
-
n2 -
The number of failure of the distribution
-
N1 -
The number of success samples of the distribution
-
N2 -
The number of failure samples of the distribution
Return Values
The probability mass at n1 or false for failure.
