<p>The <code>lep</code> data frame has 1370 rows and 7 columns. This was an
unmatched case-control study in which incident cases of leprosy in a
region of N. Malawi were compared with population controls.</p>

datasets

Functions for demographic and epidemiological analysis in
the Lexis diagram, i.e. register and cohort follow-up data. In
particular representation, manipulation, rate estimation and
simulation for multistate data - the Lexis suite of functions, which
includes interfaces to 'mstate', 'etm' and 'cmprsk' packages.
Contains functions for Age-Period-Cohort and Lee-Carter modeling and
a function for interval censored data and some useful functions for
tabulation and plotting, as well as a number of epidemiological data
sets.
