06/13/2023, 12:29 PMHey @Patrick ,
It seems that your signal is really stable.
Have you tried using StatsForecast baseline models?

Patrick
06/13/2023, 12:29 PMno, I am using the anomaly detection model
Patrick
06/13/2023, 12:30 PManother one

06/13/2023, 12:31 PMYou can use baselines for anomaly detection too.

Patrick
06/13/2023, 12:31 PMok, I am following the example basically.
Patrick
06/13/2023, 12:31 PMI see that I need to change my whole approach again as it expects a numpydarray
Patrick
06/13/2023, 12:32 PMCan you anyway answer the inital question? It’s not on me or whats the error there?
Patrick
06/13/2023, 12:32 PMdo i need more data?
Patrick
06/13/2023, 12:34 PMmore data leads to that

You might be able to try a simpler model for the trend instead of the underlying AutoETS, from your plots it is not very clear if you have seasonalities.
I recommend you to start with a simpler model than MSTL.

06/13/2023, 12:37 PMok anyway, why is the Y axis not correct? Can you spot any error?
Patrick
06/13/2023, 12:39 PMWell the season_length is definitly not correct in my code. but this docu tbh is also not easy to read through woow
Patrick
06/13/2023, 12:41 PMTrying to go thorugh it and it is pretty hard to get started here

06/13/2023, 12:45 PMdo you have a discord or something for a voice chat?
Patrick
06/13/2023, 12:50 PMnot sure if this is a bug too:
Probably the factory isn’t working?

06/13/2023, 4:09 PMRegarding you initial question:
• y should be the original value coming from your data. If the Y-Axis only shows values between 3,1,2 its probably because that is the data that you have. (To be clear, y is not applying any modification to your data frame)
• Could you please validate your data by doing other plots (line or distributions) or even counting unique values?
