how can be sure my data stationary and have seasonal ? is this reasonable to get both ?

Hey @marah othman! Detecting seasonality can be done using the

ETS

model, here’s an example: https://robjhyndman.com/hyndsight/detecting-seasonality/. Regarding stationarity, you can use the kpss test available in tsfeatures (https://github.com/Nixtla/tsfeatures/blob/main/tsfeatures/tsfeatures.py#L35)

thank you i will see and`train_trajectories`
