If your test statistic exceeds a essential value, we reject the null hypothesis, indicating that the real difference in the forecast accuracy is statistically important.

We will also explicitly set the Home windows, seasonal_deg, and iterate parameter explicitly. We can get a worse healthy but This really is just an illustration of how to pass these parameters to your MSTL course.

We develop a time series with hourly frequency that includes check here a day by day and weekly seasonality which comply with a sine wave. We exhibit a far more authentic entire world example afterwards inside the notebook.

Home windows - The lengths of each seasonal smoother with respect to every interval. If these are typically big then the seasonal part will show a lot less variability as time passes. Have to be odd. If None a list of default values based on experiments in the original paper [1] are employed.
