It does this by evaluating the prediction mistakes of The 2 designs around a specific period of time. The check checks the null speculation which the two versions hold the same general performance on normal, towards the choice that they don't. In the event the take a look at statistic exceeds a crucial price, we reject the null speculation, indicating that the real difference from the forecast precision is statistically significant.

We will likely explicitly set the Home windows, seasonal_deg, and iterate parameter explicitly. We can get a worse in shape but This really is just an illustration of the way to go these parameters for the MSTL class.

windows - The lengths of every seasonal smoother with regard to each time period. If these are large then the seasonal part will present significantly less variability after some time. Have to be odd. If None a set of default values determined by experiments in the initial paper [1] are applied.
