stan_demo: Demonstrate examples included in Stan

Description

Stan includes a variety of examples and most of the BUGS example models that are translated into Stan modeling language. One example is chosen from a list created from matching user input and gets fitted in the demonstration.

Usage

stan_demo(model = character(0), 
            method = c("sampling", "optimizing", "meanfield", "fullrank"), ...)

Value

An S4 object of stanfit, unless model = 0, in which case a character vector of paths to available models is returned.

Arguments

model: A character string for model name to specify which model will be used for demonstration. The default is an empty string, which prompts the user to select one the available models. If model = 0, a character vector of all models is returned without any user intervention. If model = i where i > 0, then the ith available model is chosen without user intervention, which is useful for testing.
method: Whether to call sampling (the default), optimizing, or one of the variants of vb for the demonstration
...: Further arguments passed to method.

Run this code

  if (FALSE) {
     dogsfit <- stan_demo("dogs") # run the dogs model
     fit1 <- stan_demo(1) # run model_names[1]
