The difference between the actual time series value and the forecast is called: forecast error. In the linear trend equation, Tt = b0 + b1t, b0 represents the: y- intercept of the trend line. The time series model that is appropriate in situations where the seasonal fluctuations do not depend upon the level of the time series is: an additive model. A time series from which the effect of season has been removed by dividing each original time series observation by the corre...
