This project is a partnership by some collaborators of the Departamento de Métodos Estatísticos (DME/UFRJ) and the Laboratório de Matemática Aplicada (LabMA/UFRJ).
Our goals are to provide consultancy for insurance companies and develop research in Actuarial Science.
In particular, our project focus on three main areas of interest:
Mortality tables modelling,
Improvement, and
Lapse risk rates.
This proposal's essential characteristic is collaborating closely with researchers from different backgrounds, such as actuaries, mathematics, demographers, and others.
