4. Develop multiplicative seasonal indices for the linear trend model developed in question 3. Use these indices to adjust predictions from the linear trend model from question 3 above for seasonal effects. Plot the predictions from this model on the graph with the original data. How well does this technique fit the data? Make forecasts for the next 12 months of 2007 using this technique. S. Which forecasting method of those that you tried do you have the most confidence for making accurate forecasts for 2007? Use MAPE (mean absolute percent error) as your criterion to Justify your decision Enrichment (5 pts): Use Optimization (and Solver in Excel) to find the optimal smoothing constantin problem 2 above (by minimizing the Mean Squared Error or MSE). - Case Study2fa20- Forecasti.

You may have to perform time series plots by years. 2. Use exponential smoothing to fit the data. Select an appropriate constant based on the variation you see in the data. Comment on the appropriateness of exponential smoothing on this data set. Plot the predictions from this model on the graph with the original data. How well does this technique it the data? Make forecasts for each month in 2007 Remember, for smoothing methods, you can only provide the forecast for the next period If you use ALL 10 years of data, that means you are providing a forecast for only lan 2007 I. I still need the forecast for the other 11 months. And you cannot do a forecast using these forecasts You will have to figure out how to use all 10 years of data to determine 12 Individual, monthly forecasts 3.
