Parameters:

value – samples from this distribution.

Returns:

output of the cumulative distribution function evaluated at value.

entropy()#

Returns the entropy of the distribution.

enumerate_support(expand=True)#

Returns an array with shape len(support) x batch_shape containing all values in the support.

property event_dim: int#
Returns:

Number of dimensions of individual events.

Return type:

expand(batch_shape)#

Returns a new ExpandedDistribution instance with batch dimensions expanded to batch_shape.

Parameters:

batch_shape (tuple) – batch shape to expand to.

Returns:

an instance of ExpandedDistribution.

Return type:

ExpandedDistribution

expand_by(sample_shape)#

Expands a distribution by adding sample_shape to the left side of its batch_shape. To expand internal dims of self.batch_shape from 1 to something larger, use expand() instead.

Returns:

An expanded version of this distribution.

Return type:

ExpandedDistribution

get_args()#

Get arguments of the distribution.

Return type:

dict

icdf(q)[source]#

The inverse cumulative distribution function of this distribution.

Parameters:

q – quantile values, should belong to [0, 1].

Returns:

the samples whose cdf values equals to q.

classmethod infer_shapes(*args, **kwargs)#

Infers batch_shape and event_shape given shapes of args to __init__().

Note

This assumes distribution shape depends only on the shapes of tensor inputs, not in the data contained in those inputs.

Parameters:
  • *args – Positional args replacing each input arg with a tuple representing the sizes of each tensor input.

  • **kwargs – Keywords mapping name of input arg to tuple representing the sizes of each tensor input.

Returns:

A pair (batch_shape, event_shape) of the shapes of a distribution that would be created with input args of the given shapes.

Return type:

tuple

log_prob(*args, **kwargs)#

Evaluates the log probability density for a batch of samples given by value.

Parameters:

value – A batch of samples from the distribution.

Returns:

an array with shape value.shape[:-self.event_shape]

Return type:

numpy.ndarray

mask(mask)#

Masks a distribution by a boolean or boolean-valued array that is broadcastable to the distributions Distribution.batch_shape .

Parameters:

mask (bool or jnp.ndarray) – A boolean or boolean valued array (True includes a site, False excludes a site).

Returns:

A masked copy of this distribution.

Return type:

MaskedDistribution

Example:

property mean: Array | ndarray | bool_ | number | bool | int | float | complex#

Mean of the distribution.

sample(key, sample_shape=())[source]#

Returns a sample from the distribution having shape given by sample_shape + batch_shape + event_shape. Note that when sample_shape is non-empty, leading dimensions (of size sample_shape) of the returned sample will be filled with iid draws from the distribution instance.

Parameters:

numpy.ndarray

shape(sample_shape=())#

The tensor shape of samples from this distribution.

Samples are of shape:

d.shape(sample_shape) == sample_shape + d.batch_shape + d.event_shape
