For a given product demand, the time series trend equation is 53 - 4x. The negative sign on the slope of the equation: O is a mathematical impossibility, o is an indication that the forecast is biased, with forecast values lower than actual values O is an indication that product demand is declining. o implies that the coefficient of determination will also be negative. O implies that the cumulative error will be negative
