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

Provides functions to analyse overdispersed
counts or proportions.  These functions should be considered as
complements to more sophisticated methods such as generalized
estimating equations (GEE) or generalized linear mixed effect
models (GLMM). aods3 is an S3 re-implementation of the
deprecated S4 package aod.
