summary.aggre

<code>summary</code> method function for <code>aggre</code> objects; see
<code>as.aggre</code> and <code>aggre</code>.

Enables computation of epidemiological statistics, including
those where counts or mortality rates of the reference population are
used. Currently supported: excess hazard models (Dickman, Sloggett,
Hills, and Hakulinen (2012) <doi:10.1002/sim.1597>), rates, mean
survival times, relative/net survival (in particular the Ederer II
(Ederer and Heise (1959)) and Pohar Perme (Pohar Perme, Stare, and
Esteve (2012) <doi:10.1111/j.1541-0420.2011.01640.x>) estimators), and
standardized incidence and mortality ratios, all of which can be
easily adjusted for by covariates such as age. Fast splitting and
aggregation of 'Lexis' objects (from package 'Epi') and other
computations achieved using 'data.table'.
