...A(3,2,1) fitted my series better than ARIMA (1,0,0) that I used to generate this... The code is: mod2<-arima(series,c(1,0,0)) plot(series,main='black=series - red=ARIMA(3,2,1) - green=ARIMA(1,0,0)') lines(fitted(mod1),col='red') lines(fitted(mod2),col='green') Did I do somothing wrong? Anyone can give me explanation?
