Merits and demerits of exponential smoothing merits: if we use the moving averages method to forecast, we need to have m past values this is cumbersome if there are many items for which forecasting is required. Definition of exponential smoothing: statistical technique for detecting significant changes in data by ignoring the fluctuations irrelevant to the purpose at hand in exponential smoothing (as opposed to in moving averages smoothing) . However, a disadvantage of the linear trend line is that it will not adjust to a change in the trend, as the exponential smoothing forecast methods will that is, it is assumed that all future forecasts will follow a straight line.
71 simple exponential smoothing the simplest of the exponentially smoothing methods is naturally called simple exponential smoothing (ses) 13this method is suitable for forecasting data with no clear trend or seasonal pattern. Exponential smoothing techniques: one of the most successful forecasting methods is the exponential smoothing (es) techniques moreover, it can be modified efficiently to use effectively for time series with seasonal patterns. To understand exponential smoothing, it helps to start with the general concept of “smoothing” and a couple of other common methods used to achieve smoothing what is smoothing smoothing is a very common statistical process.

Exponential smoothing and non-negative data abstract: the most common forecasting methods in business are based on exponential smoothing and the most common time series in business are inherently non-negative. Exponential smoothing methods are averaging methods (in fact, exponential smoothing is a short name for an exponentially weighted moving average) that require only three pieces of data: the forecast for the most recent time period (ft), the actual value for that time period (yt) and the value of the smoothing constant (denoted by ().
