Hi
so
var.2c <- VAR(Canada, p = 2, type = "const")
irf(var.2c, impulse = "e", response = c("prod", "rw", "U"), boot = FALSE)
works only sometimes? Or it does not work with **your** data only?
If it is the later, the issue is probably in your data. You should look at them
to see if
str(yourdata)
does not show some problems.
Cheers
Petr
