- What are forecasting methods?
- How the forecasting methods are used differently between consensus and statistical forecasting.
Forecasting Methods Definition
A forecasting method is the category of forecasting which is being applied.
- Time series forecasting (such as exponential smoothing, and moving average)
- Consensus-based forecasting (the Delphi method, and prediction markets) are also methods.
- Causal forecasting is a method of forecasting where independent variables are selected in order to predict dependent variables.
Forecasting methods can be confused with a forecasting model, which is most often used to describe the specific mathematical formula used to develop a forecasting in either time series or causal forecasting. The model is differentiated from the forecasting parameters which then control the model in its development of the forecast.
How is a Forecast Method Different from a Forecast Model?
Forecasting models are the specific or exact procedure that was used to create the forecast. A three-period moving average is a model while a two-period moving average is another model, both of which are within the time series forecasting method.
Forecasting models are subordinate to, or children of parent forecasting methods.
Forecasting models are strongly associated with statistical forecasting, and not consensus-based forecasting or collaborative forecasting.
