Gets a character vector of the names of the available distributions.

Usage

ssd_dists(bcanz = NULL, tails = NULL, npars = 2:5, valid = TRUE)

Arguments

bcanz

A flag or NULL specifying whether to only include distributions in the set that is approved by BC, Canada, Australia and New Zealand for official guidelines.

tails

A flag or NULL specifying whether to only include distributions with both tails.

npars

A whole numeric vector specifying which distributions to include based on the number of parameters.

valid

A flag or NULL specifying whether to include distributions with valid likelihoods that allows them to be fit with other distributions for modeling averaging.

Value

A unique, sorted character vector of the distributions.
