Hi! Is any of the models included in StatsForecast able to handle multivariate time series?

Hi @Germán Abrevaya if by multivariate you mean multiple series, all statsforecast's models allow you to forecast multiple series at once (just add a unique_id for them). If you mean with exogenous variables, then only some of the models allow this, namely the AutoARIMA & the MSTL-AutoARIMA. Here's a how to guide in case you haven't seen it. https://nixtla.github.io/statsforecast/docs/how-to-guides/exogenous.html

Hi Mariana, thanks for your response! With multivariate, I don’t mean a single variable that is the primary one with the rest being secondary. I mean multiple coupled variables that are all equally relevant and are all targets for the forecast. For example, a dynamical system with multiple state variables.

ok, I guess what you need is something like a VAR model? If so, statsforecast doesn't support it yet, but if you need it please open an issue in GitHub and we'll try to work on it soon. Here's the link: https://github.com/Nixtla/statsforecast/issues

Hi Mariana, if all statsforecast models allow us to forecast multiple series at once, is it possible to parallelize this process through PySpark/Spark?
m
Yes, here's a tutorial and an example for Spark.
