jax.random.lognormal#

jax.random.lognormal(key, sigma=1.0, shape=None, dtype=<class 'float'>)[source]#

Sample lognormal random values with given shape and float dtype.

The values are distributed according to the probability density function:

\[f(x) = \frac{1}{x\sqrt{2\pi\sigma^2}}\exp\left(-\frac{(\log x)^2}{2\sigma^2}\right)\]

on the domain \(x > 0\).

Parameters:
Return type:

Array

Returns:

A random array with the specified dtype and with shape given by shape.
