SARIMAX as extended AR(I)MAX?
Though I have not found the solution anywhere I have come up with a trick that I will post here for future reference: As long as you only want to include AR terms of the external variables (even the dependant variable can be used as an external variable) it is possible to manually lag the variables and then put them together by using ts.union(). Then the normal ARIMA function can be used to solve this problem. -- View this message in context: http://r.789695.n4.nabble.com/SARIMAX-as-extended-AR-I-MAX-tp3898726p3947880.html Sent from the R help mailing list archive at Nabble.com.
