True (Time-series forecasting, easy) 11. One advantage of exponential smoothing is the limited amount of record keeping involved. True (Time-series forecasting, moderate) 12. The larger the number of periods in the simple moving average forecasting method, the greater the method's responsiveness to changes in demand. False (Time-series forecasting, moderate) 13. Forecast including trend is an exponential smoothing technique that utilizes two smoothing constants: one for the average level of the forecast and one for its trend. True (Time-series forecasting, easy) 14. Mean Squared Error and Coefficient of Correlation are two measures of the overall error of a forecasting model. False (Time-series forecasting, easy) 15. In trend projection, the trend component is the slope of the regression equation. True (Time-series forecasting, easy) 16. In trend projection, a negative regression slope is mathematically impossible. False (Time-series forecasting, moderate) 17. Seasonal indexes adjust raw data for patterns that repeat at regular time intervals. True (Time-series forecasting, moderate) 18. If a quarterly seasonal index has been calculated at 1.55 for the October-December quarter, then raw data for that quarter must be multiplied by 1.55 so that the quarter can be fairly compared to other quarters. False (Time-series forecasting: Seasonal variation in data, moderate) 19. The best way to forecast a business cycle is by finding a leading variable. ... View Full Document
