In Exponentially Smoothed Time Series,the Smoothing Constant W Is Chosen

Multiple Choice

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
