Alpha smoothing factor. Present an example of first-order exponential smoothing. Exponential smoothing factor, also known as the smoothing coefficient or alpha (α), is a parameter used in exponential smoothing models to control the weightage given to the past observations while forecasting future values. For simple exponential smoothing, there is only one smoothing parameter (α), but for the methods that follow there are usually more than one smoothing parameter. Aug 25, 2025 · Simple Smoothing is a forecasting method used for time series data that does not exhibit a trend or seasonality. It relies on univariate data and uses a single parameter called alpha (α α) or the smoothing factor. Mar 30, 2025 · At the heart of exponential smoothing lies the Alpha Factor, a pivotal component that determines the weight given to the most recent observation in time series data.
