This repo contains one notebook in which I do demand forecast on a Kaggle competition dataset ( from the Store Item Demand Forecasting Challenge)using smoothing methods, Prophet (+Neural Prophet), ARMA (and several of its versions).
How to use it: Open the Jupyter Notebook in this folder. You can clone it, download it or just read it here. There is also a link at the top of the Notebook which takes you to the same Notebook on Kaggle.
