when should you not decompose a time series? what observation in statl results might in you experience indicate a faulty/useless decomposition when should you use stl decomposition when do you use stl decomposition why is it important to use a static analysis for stl why do you not use static analysis when you can when to not use stl decomposition when to not apply static decomposition when should you not use stl decomposition when is the best time to use a static time series which of the following might in a stl result indicate a faulty/useless decomposition? which statement might indicate a faulty/useless decomposition? when should stl decompose results what to use in static decomposition why is it useful to use static analysis when should you not use stl decomposition when should you not apply static decomposition when should you not apply stl in time series when to use stl decomposition and if not, what observation might indicate a faulty/useless decomposition when is it appropriate to do stl decomposition?
