Hi, I have a similar question: ir <- irf(varsumm, impulse=c("prod", "rea", "rpo") n.ahead=20, runs=500, ci=0.95)
will calculate the orthogonalized impulse responses from "prod", "rea", and "rpo", i.e. a (1, 1, 1)' vector. What do I need to do to make the impulse (-1, 1, 1)', i.e. I want the the first shock to be negative 1 unit?
