If you're using Excel, you're in luck, because it offers some great tools to make exponential smoothing a breeze. Exponential smoothing is a method in statistics used for smoothing time series data by assigning exponentially Method 2 – Applying FORECAST. In Excel, exponential smoothing can be a powerful tool for making accurate predictions and decision-making based on historical data. This is a way of “Smoothing” out the data by eliminating much of random effects. The basic idea is that time series data often has “random noise” associated with it, which leads to peaks and valleys in the data, but by applying exponential smoothing we can smooth out these peaks and valleys to see the true underlying trend of the Where = step forecast, = current period level forecast, = current period data, = level smoothing coefficient.

Seasonal cycles are patterns in the data that occur over a standard number of observations. To optimize your forecast, whether moving average, exponential smoothing or another form of a forecast, you need to calculate and evaluate MAD, MSE, RMSE, and MAPE. ETS function predicts a value based on existing values that follow a seasonal trend. However, this algorithm performs smoothing by detecting seasonality patterns and confidence intervals. With Excel 2016 or later, this is easy to do. 3. Exponential smoothing gives more weight to the most recent observations and reduces exponentially as the distance from the observations rises, with the premise that the future will be similar to the Learn Excel's exponential smoothing effortlessly for stellar forecasts. you want to calculate the forecast values for 2023.
