"February 1983." Includes bibliographic references. "This paper first compares the forecasting errors recorded when an autoregressive integrated moving average (ARIMA) model of Box and Jenkins (1970) is fitted to seasonally unadjusted series on the one hand and to seasonally adjusted series on the other hand. The errors are not systematically lower with seasonally unadjusted data. However, it is definitely easier to identify and fit models to unadjusted than to adjusted series"--Abstract.
