Rolling-window analysis of a time-series model assesses: The stability of the model over time. A common time-series model assumption is that the coefficients are constant with respect to time. Checking for instability amounts to examining whether the coefficients are time-invariant. ...

A time series model has a single parent node that represents the model and its metadata. Underneath that parent node, there are one or two time series trees, depending on the algorithm that you used to create the model.If you create a mixed model, two separate trees ar...
