Model-average marginal posterior distributions and marginal Bayes factors

Description

Creates marginal model-averaged and conditional posterior distributions based on a list of models, vector of parameters, formula, and a list of indicators of the null or alternative hypothesis models for each parameter. Computes inclusion Bayes factors for each marginal estimate via a Savage-Dickey density approximation.

Usage

marginal_inference(
  model_list,
  marginal_parameters,
  parameters,
  is_null_list,
  formula,
  null_hypothesis = 0,
  normal_approximation = FALSE,
  n_samples = 10000,
  seed = NULL,
  silent = FALSE
)

Arguments

model_list	list of models, each of which contains marginal likelihood estimated with bridge sampling marglik and prior model odds prior_weights
marginal_parameters	parameters for which the the marginal summary should be created
parameters	all parameters included in the model_list that are relevant for the formula (all of which need to have specification of is_null_list)
is_null_list	list with entries for each parameter carrying either logical vector of indicators specifying whether the model corresponds to the null or alternative hypothesis (or an integer vector indexing models corresponding to the null hypothesis)
formula	model formula (needs to be specified if parameter was part of a formula)
null_hypothesis	point null hypothesis to test. Defaults to 0
normal_approximation	whether the height of prior and posterior density should be approximated via a normal distribution (rather than kernel density). Defaults to FALSE.
n_samples	number of samples to be drawn for the model-averaged posterior distribution
seed	seed for random number generation
silent	whether warnings should be returned silently. Defaults to FALSE

Value

mix_posteriors returns a named list of mixed posterior distributions (either a vector of matrix).
