compute_variance_decompositions.PosteriorBVARGROUPPANEL: Computes posterior draws of the forecast error variance decomposition

Description

For each country, each of the draws from the posterior estimation of the model is transformed into a draw from the posterior distribution of the forecast error variance decomposition.

Usage

# S3 method for PosteriorBVARGROUPPANEL
compute_variance_decompositions(posterior, horizon)

Value

An object of class PosteriorFEVDPANEL, that is, a list with C elements containing NxNx(horizon+1)xS arrays of class PosteriorFEVD with S draws of country-specific forecast error variance decompositions.

Arguments

posterior

posterior estimation outcome - an object of class PosteriorBVARGROUPPANEL obtained by running the estimate function.

horizon

a positive integer number denoting the forecast horizon for the forecast error variance decompositions.

Examples

# specify the model and set seed
specification  = specify_bvarGroupPANEL$new(            # specify the model
                  ilo_dynamic_panel[1:5],
                  group_allocation = country_grouping_region[1:5]
                )

# run the burn-in
burn_in        = estimate(specification, 5)

# estimate the model
posterior      = estimate(burn_in, 5)
