Impulse response function in SVAR and Var

[Thomas Lee]

HI everyone, i want to implement the negative shock in IRF impulse response function. Is this possible ? The default is the positive shock. Thanks a lot

Hi !

Why would you want to do this ?

If things are well done, what is true for a positive shock is also for a negative shock. It's symetric.
