(n, p, size=None, dtype=<class 'int'>)[source]¶ Negative binomial distribution.
Returns an array of samples drawn from the negative binomial distribution. Its probability mass function is defined as
\[f(x) = \binom{x + n - 1}{n - 1}p^n(1-p)^{x}.\]Parameters: - n (int) – Parameter of the negative binomial distribution \(n\).
- p (float) – Parameter of the negative binomial distribution \(p\).
- 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 negative binomial distribution.
