jax.random.weibull_min

jax.random.weibull_min(key, scale, concentration, shape=(), dtype=None)

Sample from a Weibull distribution.

The values are distributed according to the probability density function:

\[f(x;\sigma,c) \propto x^{c - 1} \exp(-(x / \sigma)^c)\]

on the domain \(0 < x < \infty\), where \(c > 0\) is the concentration parameter, and \(\sigma > 0\) is the scale parameter.

Parameters:

• key (ArrayLike) – a PRNG key.

• scale (RealArray) – The scale parameter of the distribution.

• concentration (RealArray) – The concentration parameter of the distribution.

• shape (Shape) – The shape added to the parameters loc and scale broadcastable shape.

• dtype (DTypeLikeFloat | None) – The type used for samples.

Returns:

A jnp.array of samples.

Return type:

Array
