% 87 persons with lupus nephritis. Followed up 15+ years. 35 deaths. Var =
% duration of disease. Over 40 baseline variables avaiable from authors.
% Description :
% For description of this data set arising from 87 persons
% with lupus nephritis followed for 15+ years after an initial
% renal biopsy (the starting point of follow-up) see the introduction to
% Abrahamowicz, MacKenzie and Esdaile (December 1996 issue).
% This data set only contains time to death/censoring, indicator,
% duration and log(1+duration), where duration is the duration
% of untreated  disease prior to biopsy. This variable was the
% focus in the aforementioned JASA article because it clearly
% violates the proportionality of hazards assumption. More than
% 40 other variables acquired at baseline are available from
% authors.
% Permission :
% This data can be freely used for non-commercial purposes and
% distributed freely.
