The following data represents quarterly shipments for a medi

The following data represents quarterly shipments for a medium sized producer of electrical drives and motors from 2013 to 2014 Use a simple exponential smoothing model to forecast the demand for each quarter of years 2013 and 2014. Use 900 as the starting forecast value (the forecast for quarter 1 of 2013) and an alpha (smoothing parameter) of 0.25. Be sure to produce a forecast for each quarter of 2013 and 2014 (first quarter of 2013 forecast will be 900) and the first quarter of 2015. Create a line chart showing both the actual and forecast values you produced. Calculate a forecast error for each period for 2013 and 2014 Calculate a MAD for each period of 2013 and 2014
