dist_mixture {reservr}

Mixture distribution

Description

Parameters of mixing components can be overridden with with_params = list(dists = list(..., ..., ...)). #' Mixing probabilites can be overridden with with_params = list(probs = list(..., ..., ...)). The number of components cannot be overridden.

Usage

dist_mixture(dists = list(), probs = NULL)

Arguments

dists

A list of mixing distributions. May contain placeholders and duplicates.

probs

A list of mixing probabilities with the same length as dists. They are normalized to sum to one and NULL can be used as a placeholder within probs. To reduce the number of required parameters, probs should at least be partly specified (probs = list(NULL, NULL, ..., 1) with k - 1 NULLs where k is the number of mixing components).

Details

Does not support the quantile() capability!

Value

A MixtureDistribution object.
