Question
When using the exponential smoothing technique to smooth a series the value of the smoothing coefficient (W) should be between -1 and 1 True False
Solution
False. The value of the smoothing coefficient (W) in the exponential smoothing technique should be between 0 and 1, not -1 and 1. This coefficient is used to weight the importance of the most recent data points. A value of 0 means that only the most recent data point is considered, while a value of 1 means that all data points are considered equally. Negative values are not used because they would give more weight to older data points, which is not the purpose of this technique.
