MathProbabilityDensityHypergeometric

Calculates the value of the probability mass function of hypergeometric distribution with the m, k and n parameters for a random variable x. In case of error it returns NaN.

Calculates the value of the probability mass function of hypergeometric distribution with the m, k and n parameters for an array of random variables x[]. In case of error it returns false. Analog of the dhyper() in R.

Parameters

x

[in]  Value of random variable.

x[]

[in]  Array with the values of random variable.

m

[in]  Total number of objects (integer).

k

[in]  Number of objects with the desired characteristic (integer).

n

[in]  Number of object draws (integer).

log_mode

[in]  Flag to calculate the logarithm of the value. If log_mode=true, then the natural logarithm of the probability density is returned.
