Abstract: Technologies are disclosed for implementing a time series forecasting model. A time series forecasting model comprising a periodic component is modified to include an event-based component comprising a long-term portion representing impacts greater than one period of the periodic component, and a short-term portion representing impacts shorter than one period of the periodic component. A forecast is output using the modified time series forecasting model.
