According to it, the one-step-ahead forecast is equal to the most recent actual value: \ [\begin {equation} \hat {y}_t = y_ {t-1} . This process is iterative, fitting the model to the data based on one-step-ahead forecasts, starting from the first observation to the last in the sample. 1 Naïve Naïve is one of the simplest forecasting methods. Consider an example with temperature forecasting. The rate at which the weights decrease is controlled by the parameter α. This predicted mean is a pandas series. 5. 6} \end {equation}\] Using this approach might sound naïve indeed, but there are cases where it is very hard to outperform.
