Data grouped in relatively wide histogram bins are frequently encountered in practice. Here, in particular, grouped data by age are considered.
We propose a penalized composite link model to estimate smooth densities by single years of age when data are provided in coarse age classes only. The performance of the model is examined in two applications: the first one illustrates mortality trajectories by age and the second studies simulated patterns of age at first marriage.
