Abstract

In Service & Pitt (2002) the authors presented a Generalised Linear Model of disability income claim termination rates based on the data from 1980 to 1998. The model was simplified for the purposes of the paper and was intended to demonstrate the possibilities of using such an approach in the preparation of “standard” tables. In this paper, the authors present a full scale GLM of incidence rates using the 1995 to 1998 data. All available characteristics present in the data are included. A comparison of the GLM with IAD89-93 shows the difference in experience between the two data periods. The significance of the individual characteristics shows the variation in the model according to the characteristics which IAD89-93 does not include. Overall the model shows a goodness of fit at a level with significance greater than 95%.
