convert_bayesian_as_frequentist: Convert (refit) a Bayesian model to frequentist

Description

Refit Bayesian model as frequentist. Can be useful for comparisons.

Usage

convert_bayesian_as_frequentist(model, data = NULL)
bayesian_as_frequentist(model, data = NULL)

Arguments

model

A Bayesian model.

data

Data used by the model. If NULL, will try to extract it from the model.

Examples

# NOT RUN {
# Rstanarm ----------------------
if (require("rstanarm")) {
  # Simple regressions
  model <- stan_glm(Sepal.Length ~ Petal.Length * Species,
    data = iris, chains = 2, refresh = 0
  )
  bayesian_as_frequentist(model)

  model <- stan_glm(vs ~ mpg,
    family = "binomial",
    data = mtcars, chains = 2, refresh = 0
  )
  bayesian_as_frequentist(model)
}
# }
# NOT RUN {

# NOT RUN {
if (require("rstanarm")) {
  # Mixed models
  model <- stan_glmer(Sepal.Length ~ Petal.Length + (1 | Species),
    data = iris, chains = 2, refresh = 0
  )
  bayesian_as_frequentist(model)

  model <- stan_glmer(vs ~ mpg + (1 | cyl),
    family = "binomial",
    data = mtcars, chains = 2, refresh = 0
  )
