Obtain samples from the posterior distribution of reported quantities

When samples from the posterior distribution are obtained using tmbstan, only the model parameters can be accessed directly from the stanfit object (i.e., derived quantities such as par_B0 or M_a cannot be accessed directly). Accessing derived quantities must be done using the this function.

Usage

get_posterior(
  object,
  posterior,
  pars = "par_B0",
  iters = NULL,
  option = 2,
  type = "df"
)

Arguments

object: A list specifying the AD object created using MakeADFun.
posterior: An rstan objected created using the tmbstan function.
pars: The parameter(s) to be extracted.
iters: The number of iterations to be extracted.
option: The parallel option to use.
type: default data frame "df" or "array"

Value

A data.frame or array
