Is there a way of running an **ARIMA/Holt-Winters model** in python that deals with multiple items (time series) at once? 

I can run a single ARIMA/Holt-Winters model using the StatsModels package in Python, but not for multiple Time Series. 

To clarify what I mean by multiple Time Series, see my dataset.
