Use the training set to implement the Holt exponential smoothing method with two sets of user-supplied smoothing parameters, = 0.20 and = 0.10 and = 0.30 and = 0.20. Compute the resulting performance measures for the validation set. Note: Do not round intermediate calculations. Round "MSE" final answers to the nearest whole number and "MAD" , "MAPE" final answers to 2 decimal places. b-1. Determine the preferred smoothing parameters for making the forecast
