It does this by evaluating the prediction problems of The 2 models about a specific period. The take a look at checks the null hypothesis the two products hold the very same effectiveness on typical, from the alternative that they do not. If your test statistic exceeds a essential benefit, we reject the null hypothesis, indicating that the main difference during the forecast precision is statistically important.

We may also explicitly set the Home windows, seasonal_deg, and iterate parameter explicitly. We can get a worse in good shape but That is just an illustration of the way to go these read more parameters for the MSTL class.

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