WebFeb 15, 2024 · 2. Double Exponential Smoothing. This method is known as Holt's trend model or second-order exponential smoothing. Double exponential smoothing is used in time-series forecasting when the data has a linear trend but no seasonal pattern. The basic idea here is to introduce a term that can consider the possibility of the series exhibiting … WebThe chosen starting values are and .
