UvMixture

UvMixture()

Weighted mixture of one or more univariate component distributions.

Attributes

Name	Description
mean	Weighted expected value of the component distributions.
support	Union of component supports.
variance	Mixture variance using the law of total variance.
x_range	Union of component plotting ranges.

Methods

Name	Description
cdf	Weighted component cumulative distribution function.
elicit	Elicit a mixture directly from component distributions and weights.
fit	Fit is not implemented for generic univariate mixtures.
pdf	Weighted component probability density/mass function.
plot	Plot the mixture CDF with a low-alpha PDF/PMF fill.
ppf	Percent point function / inverse CDF is not implemented for mixtures.
sample	Generate samples by first choosing a component, then sampling from it.
validate_mixture	Validate component and weight shapes, then normalize weights.

cdf

UvMixture.cdf(x)

Weighted component cumulative distribution function.

elicit

UvMixture.elicit(components, weights, name=None)

fit

UvMixture.fit(data, **kwargs)

Fit is not implemented for generic univariate mixtures.

pdf

UvMixture.pdf(x)

Weighted component probability density/mass function.

plot
