summary.PosteriorFEVD {bsvars}

Provides posterior summary of forecast error variance decompositions

Description

Provides posterior means of the forecast error variance decompositions of each variable at all horizons.

Usage

## S3 method for class 'PosteriorFEVD'
summary(object, ...)

Arguments

object

an object of class PosteriorFEVD obtained using the compute_variance_decompositions() function containing draws from the posterior distribution of the forecast error variance decompositions.

...

additional arguments affecting the summary produced.

Value

A list reporting the posterior mean of the forecast error variance decompositions of each variable at all horizons.

Examples

# upload data
data(us_fiscal_lsuw)

# specify the model and set seed
set.seed(123)
specification  = specify_bsvar$new(us_fiscal_lsuw)

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

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

# compute forecast error variance decompositions
fevd           = compute_variance_decompositions(posterior, horizon = 4)
fevd_summary   = summary(fevd)
