In the following sections, you will first learn about residuals and errors. You will then learn about two evaluation metrics, the MAE and RMSE, and how they are used to evaluate regression models.

Residuals and Errors

The residual refers to the difference between the value predicted by the model and the true value for a data point. It can be thought of as by how much your model missed a particular value.
