standard_exponential
(size=None, dtype=<class 'float'>)[source]¶ Standard exponential distribution.
Returns an array of samples drawn from the standard exponential distribution. Its probability density function is defined as
\[f(x) = e^{-x},\]Parameters: - 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.float32
andnumpy.float64
types are allowed.
Returns: Samples drawn from the standard exponential distribution.
