expand.data

This is a utility function. 
The original records with <code>first.well</code>, <code>last.well</code> and
 <code>first.ill</code> are
 expanded to multiple records; several for each interval where the
 person is known to be well and one where the person is known to fail.
 At the same time columns for the covariates needed to estimate rates
 and the response variable are generated.

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.
