WebResiduals. The “residuals” in a time series model are what is left over after fitting a model. For many (but not all) time series models, the residuals are equal to the difference between the observations and the corresponding fitted values: \[ e_{t} = y_{t}-\hat{y}_{t}. Residuals are useful in checking whether a model has adequately captured the information in the data.
