Mixture distribution.

A weighted mixture of component distributions, optionally zero-inflated. Mirrors the C# Mixture composite.

Parameters

Name	Type	Description	Default
components	sequence of Distribution	The mixture components.	required
weights	array-like of float	Mixture weights, the same length as components.	required
zero_inflated	bool	Whether the mixture places extra probability mass at zero.	False
zero_weight	float	The probability mass at zero when zero_inflated is True; ignored otherwise.	0.0

Returns

Name	Type	Description
	Distribution	Family "Mixture", accepted by every method every other :class:Distribution accepts.

>>> d = dist_mixture(
...     [Distribution("Normal", [0, 1]), Distribution("Normal", [5, 1])],
...     weights=[0.5, 0.5],
... )
>>> d.pdf(2.5) > 0
