jax.random.pareto(key, b, shape=None, dtype=<class 'numpy.float64'>)[source]ΒΆ

Sample Pareto random values with given shape and float dtype.

  • key (Union[Any, PRNGKeyArray]) – a PRNG key used as the random key.

  • b (Any) – a float or array of floats broadcast-compatible with shape representing the parameter of the distribution.

  • shape (Optional[Sequence[int]]) – optional, a tuple of nonnegative integers specifying the result shape. Must be broadcast-compatible with b. The default (None) produces a result shape equal to b.shape.

  • dtype (Any) – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).

Return type



A random array with the specified dtype and with shape given by shape if shape is not None, or else by b.shape.
