6  Linear Trend: S t = S 0 + b t b = Growth per time period  Constant Growth Rate S t = S 0 (1 + g) t g = Growth rate  Estimation of Growth Rate lnS t = lnS 0 + t ln(1 + g)

7 Ratio to Trend Method Actual Trend Forecast Ratio = Seasonal Adjustment = Average of Ratios for Each Seasonal Period Adjusted Forecast = Trend Forecast Seasonal Adjustment

8 Ratio to Trend Method: Example Calculation for Quarter 1 Trend Forecast for = (0.394)(17) = Seasonally Adjusted Forecast for = (18.60)(0.8869) = 16.50

9 Forecast is the average of data from w periods prior to the forecast data point.

10 Forecast is the weighted average of of the forecast and the actual value from the prior period.

11 Measures the Accuracy of a Forecasting Method
