[R] How could I specify "no interception term" in arima?

[Rui Barradas]

Hello,

In fact, it's written there, in ?arima:

"Further, if include.mean is true (the default for an ARMA model), this 
formula applies to X - m rather than X."

So, use include.mean = FALSE


Hope this helps,

Rui Barradas
