Create a Declared-Prior versus Posterior Bridge

Compares marginal draws from the recorded gp3bayes prior specification with fitted posterior draws on the same parameter scale.

Usage

prior_posterior_bridge(
  fit,
  variables = NULL,
  regex = "^(b_|sd_|cor_|sigma$)",
  ndraws = 4000L,
  probs = c(0.025, 0.5, 0.975),
  seed = 1L
)

Arguments

fit

A fitted gp3bayes_fit.

variables

Optional exact posterior variables.

regex

Optional posterior-variable regular expression.

ndraws

Number of prior draws and maximum posterior draws used.

probs

Three interval probabilities.

seed

Non-negative integer seed.

Value

A gp3bayes_prior_posterior_bridge.
