dear splus-experts,
i am running a kaplan-meyer survival analysis on an large data set
(splus2000 on win98), no problem when wanting to produce a plot with a
single "curve".
now the problem: does anybody know of a way to include a covariate (e.g.
3 catgories), so that in this case 3 "curves" for each condition are
plotted right away (so far i managed to do this not very elegantly by
splitting the dataset by the covariate, running the survival on all
subsets and copying/pasting together the plots).
any comment is highly appreciated.
thanks.
