Question 2
In exponentially smoothed time series, the smoothing constant w is chosen on the basis of how much smoothing is required. In general, which of the following statements is true?
a. A small value of w such as w = 0.1 results in very little smoothing, while a large value such as w = 0.8 results in too much smoothing
b. A small value of w such as w = 0.1 results in too much smoothing, which a large value such as w = 0.8 results in very little smoothing
c. A small value of w such as w = 0.1 and a large value such as w = 0.8 may both result in very little smoothing
d. A small value of w such as w = 0.1 and a large value such as w = 0.8 may both result in too much smoothing
