rstanarm (version 2.9.0-3)

example_model: Example model

Description

A pre-fit model for use in rstanarm examples.

format

A stanreg object containing the output from fitting the model in the Examples section, below. The chains and iter arguments are specified to make this example be small in size. In practice, we recommend that they be left unspecified in order to use the default values (4 and 2000 respectively) or increased if there are convergence problems. The cores argument is optional and on a multicore system, the user may well want to set that equal to the number of chains being executed.

cbpp for a description of the data.

Examples

example_model <- 
  stan_glmer(cbind(incidence, size - incidence) ~ size + period + (1|herd),
             data = lme4::cbpp, family = binomial,
             # this next line is only to keep the example small in size!
             chains = 2, cores = 1, seed = 12345, iter = 500)
