cohorts

Number of prostate cancer deaths and midperiod population for nonwhites in the USA by age and period.
  The cohort index $k$ is related to age and period indices ($i$ and $j$, respectively) by $k = j + I - i$, 
  where $I = max(i)$ (Holford, 1983, Table 2).

datasets

This package provides a set of functions to analyse
        overdispersed counts or proportions. Most of the methods are
        already available elsewhere but are scattered in different
        packages. The proposed functions should be considered as
        complements to more sophisticated methods such as generalized
        estimating equations (GEE) or generalized linear mixed effect
        models (GLMM).
