What type of pattern exist in the data? b) Develop three-quarter moving average forecasts for this time series. c) Use a = .4 to compute the exponential smoothing values for the time serries and provide forecasts. d) Use a multiple regression model to develop an equation to account all type of patterns in data. e) Provide a forecast for spring of year 4, using the all three techniques. f) Calculate MSE for all three techniques and determine the best forecasting method for this time series
