(ngood, nbad, nsample, size=None, dtype=<class 'int'>)[source]¶ hypergeometric distribution.
Returns an array of samples drawn from the hypergeometric distribution. Its probability mass function is defined as
\[f(x) = \frac{\binom{m}{n}\binom{N-m}{n-x}}{\binom{N}{n}}.\]Parameters: - ngood (int or array_like of ints) – Parameter of the hypergeometric distribution \(n\).
- nbad (int or array_like of ints) – Parameter of the hypergeometric distribution \(m\).
- nsample (int or array_like of ints) – Parameter of the hypergeometric distribution \(N\).
- size (int or tuple of ints) – The shape of the array. If
None
, a zero-dimensional array is generated. - dtype – Data type specifier. Only
numpy.int32
andnumpy.int64
types are allowed.
Returns: Samples drawn from the hypergeometric distribution.
Return type: See also
