dpinar: DP-INAR model training

In heltongraziadei/BINAR: BINAR model package

Description

Computes the posterior distribution for the DP-INAR family using a Gibbs sampler.

Usage

dpinar(time_series, prior = list(a_alpha = NULL, b_alpha = NULL, a_tau =
  NULL, b_tau = NULL, a0 = NULL, b0 = NULL, lambda_max = NULL),
  burn_in = 10^3, chain_length = 10^4, random_seed = 1761,
  verbose = TRUE)

Arguments

time_series	A univariate time series.
prior	List of prior hyperparameters where: a_alpha, b_alpha Hyperparameters of the thinning component. a_tau, b_tau Hyperparameters of the concentration parameter with Gamma prior. a0, b0 Base measure hyperparameters. lambda_max Hyperparameter of the uniform distribution that minimizes the corresponding D-KL.
burn_in	Number of iterations for the "burn-in" period which are discarded in the chain.
chain_length	Number of iterations of the chain.
random_seed	Value of the random seed generator.
verbose	If TRUE log info is provided.

Value

dpinar returns an object of class "dpinar".
