spey.backends.distributions.Normal

class spey.backends.distributions.Normal(loc: ndarray, scale: ndarray, weight: Callable[[ndarray], float] | float = 1.0, domain: slice = slice(None, None, None))

Normal distribution

Parameters:

• loc (np.ndarray) – Mean of the distribution.

• scale (np.ndarray) – standard deviation.

• weight (Callable[[np.ndarray], float] or float, default 1.0) – weight of the distribution.

• domain (slice, default slice(None, None)) – set of parameters to be used within the distribution.

__init__(loc: ndarray, scale: ndarray, weight: Callable[[ndarray], float] | float = 1.0, domain: slice = slice(None, None, None))

Methods

expected_data()	The expectation value of the Normal distribution.
log_prob(value)	Compute log-probability
sample(value, sample_size)	Generate samples

Attributes

weight	Weight of the distribution
domain	Which parameters should be used during the computation of the pdf
