Evaluation Metrics

Learn the main evaluation metrics for time series forecasting and how to calculate them.


Although looking at actual vs. predicted graphs can give us a general idea of whether models work well, that's not enough to properly evaluate and compare models. To do that, we need some sort of objective metric that allows us to quantify the quality of the forecasts. That is where evaluation metrics can help us.

These metrics will usually be a way to measure how distant our predictions are from the actual values for any given moment in time. The bigger that distance, the greater the error.
