Hi all
I have been searching on the web in vain. I want to include a dummy
variable in my ARIMA model. Let's say that I want to make an AR(1) model
for X including a dummy variable which should be 1 for observation 4,5,6
and zero otherwise (let's say that there is 50 observations in total). How
do I make that?
This does the trick but seems inefficient: dummy<-c(rep(0,3), rep(1,3),
rep(0,44))
Thx in advance
Best regards
/Mikael
