Methods of Studying the Risk Process in Disability Insurance

The aim of this study is to find suitable methods for utilizing available statistical information on the risk development of terminated insurances. This information may comprise not only data respecting sex, age, insurance tariff, etc., but also the points of time when certain events--disability, injuries or damages--have occurred as well as their durability and cause. The method study here presented is based on statistical material gathered from long-term disability insurances which have ceased to be valid, either in consequence of the expiration of the term of insurance, or the insured's death. We endeavor to study the point of time when the first event (disability) occurred and the relation between subsequent events, searching suitable methods for assessing risks after the occurrence of the primary event.
