  verbose = TRUE)

Arguments

time_series

A univariate time series.

prior

List of prior hyperparameters where:

a_alpha

Hyperparameters of the thinning component.

a0_tau, b0_tau

Hyperparameters of the concentration parameter Gamma prior.

a0_G0, b0_G0

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".
