exponential smoothing‚ and time series regression. For moving averages and weighted moving averages‚ use only the data for the past three fiscal years. For weighted moving averages‚ assign a value of 1 to the data for 20 X 2‚ a value of 2 to the data for 20 X 3‚ and a value of 3 to the data for 20 X 4. For exponential smoothing‚ assume that the last forecast for fiscal year 20 X 4 was $6‚300‚000. You decide on the alpha to be used for exponential smoothing. For time series regression‚ use the data

be divided into two categories: time series models and causal models. Quantitative Methods Time Series Models Causal Models Time series models look at past patterns of data and attempt to predict the future based upon the underlying patterns contained within those data. Causal models assume that the variable being forecasted is related to other variables in the environment. They try to project based upon those associations. TIME SERIES MODELS Model Description Naïve

seem better? 4.18. Consider the following actual (A1) and forecast (F1) demand levels for a product: Time Period (t) Actual Demand (A1) Forecast Demand (F1) 1 50 50 2 42 50 3 56 48 4 46 50 5 49 The first forecast F1 was derived by observing A1 and setting F1 equal to A1. Subsequent forecasts were derived by exponential smoothing. Using the exponential smoothing method‚ find the forecast time for period 5. (Hint: You need to first find the smoothing constant‚ α.) To find α: 50= 50 + α(42-50)

for a division with a brand new product‚ but it would not be as helpful or efficient for a division where there has been steady growth and established products for the past five years. The other suggestion I have would be to not begin the market analysis with reviewing the sales in each division of the company. If he would like to know more about the market‚ it would make more sense to use the build-up approach to conduct primary research. It would benefit the company because certain divisions are

co-owner Amit wants to forecast by exponential smoothing by initially setting February’s forecast equal to January’s sales with α=1. Co-owner Barbara wants to use a three-period moving average. 1. Is there a strong lineal trend in sales over time? 2. Fill in the table with what Amit and Barbara each forecast for May and the earlier months‚ as relevant. 3. Assume that May’s actual sales figure turns out to be 405. Complete the table’s columns and then calculate the mean absolute
