run_sampler_non_auxiliary(prepared_data, hyperparams = NULL,
  inits = NULL, n_chains = 1, n_draws = 1000, burn_in = 0,
  thin = 0, seed = 1)

Arguments

prepared_data

A named list generated by prepare_data function comprising model input data.

hyperparams

A named list of user-defined hyperparameters; this list should contain some or all of the following named values: alpha_psi_CM (prior shape parameter for psi_CM (inverse gamma distribution)), beta_psi_CM (prior scale parameter for psi_CM (inverse gamma distribution)), alpha_psi_CP (prior shape parameter for psi_CP (inverse gamma distribution)), beta_psi_CP (prior scale parameter for psi_CP (inverse gamma distribution))); for a given hyperparameter, default values are used if no user-defined value is provided to the function call (alpha_psi_CM := 1.5, beta_psi_CM := 1.5, alpha_psi_CP := 1.5, beta_psi_CP := 1.5).

inits

A named list of user-defined initial values to begin each MCMC chain (each element of this list should comprise a vector of length equal to the number of chains and each element of the vector should correspond to the initial value for that parameter for each chain); this list should contain some or all of the following named values: theta (defaults to randomly generated value from uniform(0.0001, 0.9999) distribution for each target candidate's corresponding theta), psi_CM (defaults to randomly generated value from prior inverse-gamma distribution for psi_CM), psi_CP (defaults to randomly generated value from prior inverse-gamma distribution for psi_CP).

n_chains

Number of MCMC chains to run; defaults to 1.

n_draws

Number of MCMC draws to run; defaults to 1000.

burn_in

Number of MCMC draws to discard from the beginning of each chain; defaults to 0.

thin

Number of MCMC draws to discard between each accepted MCMC draw for each chain; defaults to 0.

seed

Seed for random number generation; defaults to 1.

Value

A list containing the MCMC draws for each model parameter for each chain.
