We are glad to announce the following talk in the ETH/UZH ZüKoSt: Seminar on Applied Statistics:

"Avoiding indirect discrimination in modeling mortality"   

by Benedikt Herwerth, SwissRe, Switzerland

Date and Time: Friday, 28.04.2023 at 15.15 h
Place: ETH Zurich, HG G 19.1

Abstract: The topic of potential discrimination in statistical and machine learning (ML) is being increasingly discussed, both by the scientific community and the wider public. In the insurance industry specifically, customers and regulators demand that individuals are treated fairly. Regulations of the European Union, for example, mandate that gender is not be used as a factor in determining the prices of policies. 
This talk is based on a method introduced in a series of papers by Lindholm et al. on "discrimination-​free insurance pricing" that address specifically the issue of potential indirect discrimination [1, 2, 3]. 
In the first part of the talk, we outline the solution by Lindholm et al., and we discuss that indirect discrimination is a topic that is subtle and can be difficult to understand for decision takers. In the second part of our talk, we present a Swiss Re internally built toolbox implementing the methodology. In the third part of our talk, we apply the methodology to model human mortality. We use public data of the German association of actuaries, which we interpret in terms of a Bayesian network describing the relation between age, gender, the smoker status and the mortality of individuals.
