compute_fitted_values.PosteriorBSVARSV function

Computes posterior draws from data predictive density

Each of the draws from the posterior estimation of models from packages bsvars or bsvarSIGNs is transformed into a draw from the data predictive density.

## S3 method for class 'PosteriorBSVARSV'
compute_fitted_values(posterior)

Arguments

• posterior: posterior estimation outcome - an object of class PosteriorBSVARSV obtained by running the estimate function.

Returns

An object of class PosteriorFitted, that is, an NxTxS

array with attribute PosteriorFitted containing S draws from the data predictive density.

Examples

# upload data
data(us_fiscal_lsuw)

# specify the model and set seed
set.seed(123)
specification  = specify_bsvar_sv$new(us_fiscal_lsuw, p = 1)

# run the burn-in
burn_in        = estimate(specification, 10)

# estimate the model
posterior      = estimate(burn_in, 20)

# compute draws from in-sample predictive density
csd     = compute_fitted_values(posterior)
