thoro

The <code>thoro</code> data frame has 2470 rows and 14 columns.
Each row represents one patient that have had cerebral angiography (X-ray of
the brain) with an injected contrast medium, either Thorotrast or
another one (the controls).

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.
