Ten days of data on the S&P Dynamic Futures Index are as follows: 3.1) Construct a time series plot. What type of pattern exists in the data? 3.2) Use trial and error to find a value of the exponential smoothing coefficient that results in a relatively small MAE. You should try at least 5 values before making any conclusions.
