Develop the forecast for the fourth quarter using a three-quarter simple moving average method Develop the forecast for the month of October using a three-month moving average method. Forecast for the month of October using Exponential smoothing with trend method for the given data using with Alpha (a) = 0.60. Delta (0) = 0.30. The exponentially smoothed trend for the month of August is TAUG = -5.2720 and the exponentially smoothed forecast that does not include trend for August is FAUG = 214.3789 respectively. Using exponential smoothing method with FMay = 258.10, the forecasts for the five months from May through September are summarized in the table below. For each month compute the mean absolute deviation, the running sum of forecast error and the tracking signal from forecast and actual data.
