Using the Python tools for reserving review

[KiY0On]

Hi,

I am seeking an advice on how to implement using the tools in this code repo. If someone were to use these tools for his company's reserving review. What would it be the best way to do?

Some concerns I have are:

1. Internal/External Audit: Let's say we are using the "Tryangle" to make the LDF selection, how should one then go about explaining the results to the audit that the selection is reasonable?
2. If some team members are not proficient in Python and so a GUI is required for their review, what would be the best approach? I have been looking at some GUI libraries within Python, but can't stop thinking that Excel is the best resolution at the end of the day as everyone is familiar with Excel.

Thank you so much for any thought or input

Point 1: There is a paper associated with Tryangle that explains the concepts behind it, linked in the README of the repo. I have no idea if it is ready for your regulatory environment.
Point 2: The work can be done in Python using chainladder-python and then write to an Excel file for review.

Sorry about the slow response, it isn't clear that creating new discussions notifies the people it should be notifying. We might want to figure out how to stay on top of these.

I'm thinking it might be worth it to publish an Excel add-in that has similar functionality to chainladder-python. I'll try to get a proof of concept set up and see if people think it is worth maintaining something like that.

Thank you. Understood. I have read the paper and do find it interesting. I almost feel like it's the scarcity of its use within the industry that makes it hard for one to adopt this.
