Hello, the powers that be decreed that my team has to work with a ridiculously large and complex regression model (1000+ predictors, interactions, etc.) .
The model input (externaly given data) changes depending on suggestions how to change the model in future regulatory settings. My team needs to assess how these changes will affect us and why certain changes within the predictions happen.
There are many, really many, interactions, levers and knobs that can influcence the outcome and even a tiny change can have big ripple effects downstream.
Before I go off and write my own suite to explain which parts of the model contribute the most to changes in predictions between model iterations I wondered if there was a package that I could start looking into for something along these lines.
