Abstract

Age specific rates are often given only for age groups that can be rather coarse. Furthermore, they tend to show complex patterns, which often can be explained by contributions of several subgroups, such as infants or the elderly. A penalized composite link model is used to decompose the complex rate trajectory into smooth additive components from grouped data. Monotonicity or shape constraints can be incorporated by special penalty matrices.
