plot_struct_shocks: Plot structural shock time series of a STVAR model

In sstvars: Toolkit for Reduced Form and Structural Smooth Transition Vector Autoregressive Models

Plot structural shock time series of a STVAR model

Description

plot_struct_shocks plots structural shock time series of a structural STVAR model. For reduced form models (not identified by non-Gaussianity), recursive identification is assumed.

Usage

plot_struct_shocks(stvar)

Arguments

stvar

object of class "stvar"

Details

Plot the time series of the structural shocks of a structural STVAR model.

Value

No return value, called for its side effect of plotting the structural shock time series.
