Special issue on Actuarial Statistics

This special issue of AStA aims to offer an overview of some relevant problems in actuarial science, involving statistical aspects. For centuries, the function of (re)insurers has been to sell risk coverage. Insurance companies charge premiums for covering these risks. The premiums are collected in advance while claim amounts are known only later.
