In kgori/sigfit: Flexible Bayesian inference of mutational signatures

Description

get_initializer_list extracts parameter values from an extraction which can be used to initialise a follow-up extraction. One use case is to use a short, single-chain extraction to initialise a longer, multi-chain extraction. This can mitigate against label switching using the "Initialization around a single mode" strategy described in the Stan documentation https://mc-stan.org/docs/2_18/stan-users-guide/label-switching-problematic-section.html

Usage

get_initializer_list(fitobj, chains = 1)

Arguments

fitobj	Result of a sigfit signature extraction.
chains	Integer indicating the number of copies of the parameter list to be returned. Used to initialize multiple chains.

Value

A list of parameter lists.
