sampler: RAMSES Sampling Structure

In wzhorton/ramses: R Auxiliary Mcmc Suite for Easy Sampling

Description

Function that fits a heirarchical model using MCMC. It requires a list of initial parameter values, a list of needed fixed values, and a list of update functions, all of which are tied together by matching element names.

Usage

sampler(inits, fixed, updates, niter, nburn,
  parms_to_save = names(inits), progress = FALSE)

Arguments

inits	list of named parameter initial values.
fixed	list of named values that remain fixed in the model.
updates	list of update functions with names matching those in parm_state.
niter, nburn	number of MCMC iterates and burnin.
parms_to_save	character vector indicating which parameters to save. Defaults to all. Use this to allow for auxiliary onjects like matrices.

Value

A matrix where each row is an MCMC iterate and each column is a parameter or part of a parameter vector.
