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. All of the...
