Usage of ARIMASim class makes me a headache. Looking at the API there seems to be no way to pass a time series. The class itself extends SimpleTimeSeries which has an appropriate constructor, but that is not available from it. Am I supposed to extend ARIMASim and provide data from there by overriding time series methods appropriately?
I am certainly miss the way, but please bear with me, I am completely new to this API and TSA.
