Logistic Growth

[zwelitunyiswa]

First of all, this is a great library. Well done!

I have a question:

I see that orbit has a logistic option for "global_trend_option". How would I let the model know that there is a maximum carrying capacity or saturation point for the estimate? Something along this line is implemented in Facebook Prophet: https://facebook.github.io/prophet/docs/saturating_forecasts.html .

In the "global_trend_option" of DLT, when you specify logistic trend, the max carrying capacity is also estimated by the model (stan). We could consider implementing user specified value in the future.

Thank you, @edwinnglabs. That would be great, as sometimes the carrying capacity is known (e.g. a hotel, or healthcare facility). Thanks again for the great work.
