Eric and Mike are forecasting data that clearly has an upward trend and seasonality. Mike recommends determining factors for each season and using those in conjunction with a double exponential forecasting procedure. Eric agrees that they could determine seasonal factors but recommends using double exponential smoothing without determining any seasonal factors but instead doing extensive testing over the alpha and beta parameters to find the best combination and that will do just as well as Mikes recommended method. Would you recommend using (choose one option):

a. Mikes method

b. Erics method

c. Neither method

d. There not enough information to tell
