# cupy.random.logseries¶

cupy.random.logseries(p, size=None, dtype=<class 'int'>)[source]

Log series distribution.

Returns an array of samples drawn from the log series distribution. Its probability mass function is defined as

$f(x) = \frac{-p^x}{x\ln(1-p)}.$
Parameters
• p (float) – Parameter of the log series 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 and numpy.int64 types are allowed.

Returns

Samples drawn from the log series distribution.

Return type

cupy.ndarray
