Impulse-response analysis is quite simple. Having estimated a vector autoregressive (VAR) model and expressed it in a vector moving-average (VMA) representation, you are able to see how a shock to variable B affects variable A in subsequent periods. You just plug in the shock in the VMA representation.

Witryna12 lis 2024 · An ideal impulse signal is a signal that is zero everywhere but at the origin (t = 0), it is infinitely high. Although, the area of the impulse is finite. The unit impulse signal is the most widely used standard signal used in the analysis of signals and systems. Continuous-Time Unit Impulse Signal Witryna22 maj 2024 · The Dirac delta function δ ( t − t 0) is a mathematical idealization of an impulse or a very fast burst of substance at t = t 0. (Here we are considering time but the delta function can involve any variable.) The delta function is properly defined through a limiting process. One such definition is as a thin, tall rectangle, of width ε:
