fit.add

Utility function. 
The model fitted assumes a piecewise constant intensity for the
 baseline, and that the covariates act additively on the rate scale.

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.
