Implementation of the Probability of Bankruptcy by Campbell, Hilscher and Szilagyi (also described in the book "Quantitative Value")

Hello everyone,

I implemented the algorithm described in the paper "In Search of Distress Risk" by John Campbell, Jens Hilscher, and Jan Szilagyi .
Link to the paper:

As outlined in the book "Quantitative Value" and in their blog post
this algorithm is much better than the previous ones in predicting bankruptcy.

Maybe I did something wrong, because my implementation gives Apple a probability of bankruptcy equals to 100%
Would you help me to verify and improve my implementation?

I hope that the Research Notebook Link above works, otherwise can somebody explain me how to share a research notebook in the forum.
I see only a button "Attach Backtest" but no "Attach Notebook".
