Predict demand using exponential smoothing with alpha


Demand for the last four months was:
Month ----Mar-Apr-May-Jun
Demand-----6---8-----10---8

A) Predict the demand for July using each of these methods:

1) A 3-period moving average
2) Exponential smoothing with alpha equal to 0.20, April forecast is 6 (use naive to begin)
3) Using the weights of .5, .3, and .2, what is the three-period weighted moving average forecast for July

B) If the naive approach had been used to predict demand for April through June, what would the MAD have been for those months?
