Looking great!!!

Great article! and I can see you’re still altering and adding sections to it. It seems you have dedicated a lot of attention to the tools used to create the model. It would be great to also write about problems you encountered and how you have solved them, as well as open questions/problems that still should be solved.

Great work, guys!
How would you tackle seasonality in your data? I saw you were using seasonal ARIMA – any other approaches you would recommend to use?

Hey guys, great work!
If I understand correctly, you’ve used ARIMA on the total failure (from all columns), correct? It will be nice to detail it a bit more in the article.
Also, which other forecasting methods would you consider using? Which of the features are the most prune for causing raven-delivery failure? or in other words – how would you reason your prediction results?
Consider writing which further actions would you recommend the family to take, in order to maximize delivery (which failures should they focus on fixing)

Very well written article! I especially liked how you detailed the different approaches, even when they didn’t work out eventually. I find this very important and useful information which is often missing in articles.
