Explanation: Forecasting is the process of making predictions of the future based on past and present data and most commonly by analysis of trends.

A commonplace example might be an estimation of some variable of interest at some specified future date. Prediction is a similar, but more general term.

A forecast error is the difference between the actual or real and the predicted or forecast value of a time series or any other phenomenon of interest. By convention, the error is defined using the value of the outcome minus the value of the forecast.
