rstanarm (version 2.26.1)

example_jm: Example joint longitudinal and time-to-event model

Description

A model for use in the rstanarm examples related to stan_jm.

Format

Calling example("example_jm") will run the model in the Examples section, below, and the resulting stanmvreg object will then be available in the global environment. 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 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.

Examples

  # set.seed(123)
  if (.Platform$OS.type != "windows" || .Platform$r_arch !="i386")
  example_jm <- 
     stan_jm(formulaLong = logBili ~ year + (1 | id), 
             dataLong = pbcLong[1:101,],
             formulaEvent = survival::Surv(futimeYears, death) ~ sex + trt, 
             dataEvent = pbcSurv[1:15,],
             time_var = "year",
             # this next line is only to keep the example small in size!
             chains = 1, seed = 12345, iter = 100, refresh = 0)
