[R] a question about arimax, please

[Erin Hodgess]

Hello!
I have about the arimax function, please:
If you see the example page, you see the following:
# Exhibit 11.6
air.m1=arimax(log(airmiles),order=c(0,1,1),seasonal=list(order=c(0,1,1),
period=12),xtransf=data.frame(I911=1*(seq(airmiles)==69),
I911=1*(seq(airmiles)==69)),
transfer=list(c(0,0),c(1,0)),xreg=data.frame(Dec96=1*(seq(airmiles)==12),
Jan97=1*(seq(airmiles)==13),Dec02=1*(seq(airmiles)==84)),method='ML')
Now the part that I am puzzled about the "transfer" argument, please. It is
supposed to be the MA order and the AR order, respectively. However, the AR
order is 0. Should that be reversed, please?
Thanks,
Erin.
