 Each stripped sub/co-routine is a plot of impulse response functions, (1 - blue line) local projection using [Òscar Jordà (2005)](https://www.aeaweb.org/articles?id=10.1257/0002828053828518); (2 - purple line) smoothed local projection using (λ = 100, for example presented below); (3 - red lines) smoothed local projection using optimal λ estimated using cross-validation method as shown in [Barnichon and Brownlees (2019)](https://www.mitpressjournals.org/doi/abs/10.1162/rest_a_00778) (red solid line is a point estimate, dashed red lines are estimated 90% confidence set).
