When using Time Series forecasting, what is true about Double
Exponential Smoothing?
Group of answer choices
The double exponential smoothing technique should not be used
for predicting seasonal data.
Double Exponential Smoothing is able to predict both a level
effect and a trend effect in the data. It is good for predicting
cyclical data.
When Alpha (level) coefficient and Gamma (trend) coefficient are
closer to .1 (rather than closer to .9), this tends to smooth the
prediction.
