APPLIED ECONOMETRIC TIME SERIES (4th edition)
time-series.netthere are several guidelines that can be very helpful in selecting the most appropriate forecasting model: 1. Looking at the time path of a series is the single most important step in forecasting the series. Examining the series allows you to see if it has a clear trend and to get a reasonable idea if the trend is linear or nonlinear. Similarly,
