The most used of all forecasting techniques. Importance of data diminishes as the past becomes more distant. 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. Trendless data can be evaluated with the help of single exponential smoothing technique. Like the regression forecast, the double exponential smoothing forecast is based on the assumption of a model consisting of a constant plus a linear trend. A) Use exponential smoothing with a smoothing constant of 0.3 to forecast the registrations at the seminar given in Problem 4.10. Each increment in the past is decreased. This technique can be implemented on time series data to make the forecast or to smooth the data for presentation. Pandas; statsmodel (for ARIMA); simple exponential smoothing is provided from pandas.
