FAQctuary 2021-1

We are pleased to share with you our first FAQctuary of the year on "ICC, deviance, AUC : What are the differences ?".

Assessing performances of different models is essential in modelling processes. Many measures exist to determine these performances and draw conclusions. This FAQctuary compares the behaviour of three measures on different datasets. The measures under consideration are the integrated concentration curve, the deviance and the area under the curve (AUC).

This FAQctuary also compares models such as GLM, GAM and GBM using different measures. It allows to have an idea of the improvement each model brings to the previous one. In our upcoming training : Insurance Analytics: A primer, the differences and improvements between these models as their advantages and drawbacks will be studied in details. More models will also be covered.
