I am looking for a way how to predict one day of certain metric and then every hour collect real stats. And as I am doing it for 3 metrics for pretty much every country on the planet, its quite some computing time to generate this prediction and I don't want to do it every hour again.
Is there way to store prediction for a day and just compare with real data every hour?
Now I am using predict function which is giving pretty good results and it works fine for 1 metric and few countries even when computed every hour, but I need to scale it to 200 countries.
Thanks for ansewers,
