%description
Versatile method for ungrouping histograms (binned count data) assuming
that counts are Poisson distributed and that the underlying sequence on a
fine grid to be estimated is smooth. The method is based on the composite
link model and estimation is achieved by maximizing a penalized
likelihood. Smooth detailed sequences of counts and rates are so estimated
from the binned counts. Ungrouping binned data can be desirable for many
reasons: Bins can be too coarse to allow for accurate analysis;
comparisons can be hindered when different grouping approaches are used in
different histograms; and the last interval is often wide and open-ended
and, thus, covers a lot of information in the tail area. Age-at-death
distributions grouped in age classes and abridged life tables are examples
of binned data. Because of modest assumptions, the approach is suitable
for many demographic and epidemiological applications. For a detailed
description of the method and applications see Rizzi et al. (2015)
