To evaluate the accuracy of each smoothing constant, we can compute the absolute deviations and MADs. Modules English ISBN Start on. The slope is A new Modeling in the Real World item was added, and the solved problems have been revised.

The only difference between causal models and time-series models is that causal models take into account any factors that may influence the quantity being forecasted.

Causal models use historical data as well. Time-series models use only historical data. Qualitative models incorporate subjective factors into the forecasting model. Judgmental models are useful when subjective factors are important. When quantitative data are difficult to obtain, qualitative models are appropriate. The Delphi technique involves analyzing the predictions that a group of experts have made, then allowing the experts to review the data again.

This process may be repeated several times. After the final analysis, the forecast is developed.

The group of experts may be geographically dispersed. MAD is a technique for determining the accuracy of a forecasting model by taking the aver- age of the absolute deviations.

MAD is important because it can be used to help increase fore- casting accuracy. The number of seasons depends on the number of time periods that occur before a pattern repeats itself. For example, monthly data would have 12 seasons because there are 12 months in a year. Quarterly data would have 4 seasons because there are 4 quarters in a year.

Daily data would have 7 seasons because there are 7 days in a week. For daily data, it is common for many retail stores to have higher sales on Saturdays than on other days of the week, and a seasonal in- dex would reflect that.

If a seasonal index equals 1, that season is just an average season.

If the index is less than 1, that season tends to be lower than average. If the index is greater than 1, that season tends to be higher than average. To remove the impact of seasonality in a time series, each observation is divided by the ap- propriate seasonal index. The resulting deseasonalized data is then used to develop a forecast. The forecast based on the trend line using the deseasonalized data is multiplied by the ap- propriate seasonal index to adjust that forecast for the seasonal component.

A centered moving average CMA should be used if trend is present in data. If an overall average is used rather than a CMA, variations due to trend will be interpreted as variations due to seasonal factors. Thus, the seasonal indices will not be accurate. However, when weighted moving av- erages were used, the MAD was 5. Moving 3-Year Abs. Using the forecasts in the previous problem we obtain the absolute deviations given in the table below.

Because a three-period average forecasting method is used, forecasts start for period 4.

MAD for moving average is 2.

MAD for weighted average is 2. Moving average forecast for February is Weighted moving average forecast for February is Thus, based on this analysis, the moving average appears to be more accurate. The forecast for February is about There are many other factors to consider, including seasonality and any underlying causal variables such as advertising budget. The total MAD is 2.

RSFE is consistently positive. Tracking signal exceeds 2 MADs at week This could indicate a problem. See the accompanying table for a comparison of the calculations for the exponen- tially smoothed forecasts using constants of 0. Students should note how stable the smoothed values for the 0. When compared to actual week 25 calls of 85, the 0.

On the basis of the forecast error, the 0. However, other smoothing constants need to be examined. If the initial forecast is 40, the forecast for time period 25 is If the initial forecast is 60, the forecast for time period 25 is This illustrates how little impact the initial forecast has on fore- casts many periods into the future when the smoothing constant is higher.
