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. 


datasets

Functions for demographic and epidemiological analysis in
the Lexis diagram, i.e. register and cohort follow-up data, in
particular representation, manipulation and simulation of multistate
data - the Lexis suite of functions, which includes interfaces to

Also contains functions for Age-Period-Cohort modeling and a
function for interval censored data and some useful functions for
