It does this by comparing the prediction errors of the two models about a certain period of time. The test checks the null speculation that the two styles possess the exact functionality on average, from the choice that they do not. In case the exam statistic exceeds a vital benefit, we reject the null hypothesis, indicating that the main difference during the forecast accuracy is statistically considerable.

We may also explicitly set the Home windows, seasonal_deg, and iterate parameter explicitly. We can get a worse healthy but This can be just an illustration of how you can go these parameters towards the MSTL class.

Home windows - The lengths of each and every seasonal smoother with respect to each period of time. If they are substantial then the seasonal component will demonstrate less variability after a while. Needs to be odd. If None a mstl.org set of default values determined by experiments in the original paper [1] are applied.
