07/26/2023, 10:45 AMHi @Max (Nixtla), in your response you mention local scalers for MLForecast but I can't find this in the documentation/code. I must be missing it. Could you share where this is? Thanks.

07/26/2023, 2:07 PMHi Andrew! In mlforecast you have to specifically tell the software which scaler to use. You can do so through this argument:
target_transforms=[LocalStandardScaler()]
See line 14 on this notebook: https://www.kaggle.com/code/fedegr/mlforecast-functime/notebook

07/26/2023, 2:09 PM@José Morales: maybe we should write a little guide or something.

07/27/2023, 8:23 AMExcellent, thanks a lot @Max (Nixtla) and @José Morales. Do you plan on implementing for exogenous features? To enable sliding/expanding window standard scaling for example.

07/27/2023, 9:04 PMThis is already possible by doing something like here https://github.com/Nixtla/mlforecast/issues/124#issue-1683960264
But we will add a built in way to do it soon
