• In order to forecast or to have a In order to forecast or to have a meaningful forecast we need to meaningful forecast we need to make the data stationarymake the data stationary

• We were able to make the data We were able to make the data stationary by using the box jenkins stationary by using the box jenkins methodmethod

Just becauseJust because

• We decided to forecast using We decided to forecast using exponential smoothing and see how exponential smoothing and see how are model would lookare model would look

ResultsResults

• Exponential Model is very close to Exponential Model is very close to what our final model determined what our final model determined

• We will have to wait and see if our We will have to wait and see if our forecasts are correctforecasts are correct
