In my study, patients might have been sick for years before the
diagnosis is made, then they can die few months later, once diagnosed,
either from their disease or because they are elderly

Hello again,
I m trying to use timereg package as suggested (R2.7.1 on XP Pro).

which
relt = time to event, rels = status 0/1/2 2=competing, 1=event of interest,
0=censored
random = covariate I want to test

Dear R users,
I d like to assess the effect of treatment covariate on a disease relapse
risk with the package cmprsk.
However, the effect of this covariate on survival is time-dependent
(assessed with cox.zph): no significant effect during the first year of
follow-up,
then after 1 year
Dear R users,
is there a way to plot predicted curves from a Cox model with a time
dependent covariates using predict, in which other significant covariates
are included with specific values ?
I use cluster(id) in this time-dep. Cox model for rows belonging to the same
patient, and this
Dear R users,
is there a way, I mean a package, to perform a competing risk model which can
handle time dependent covariates ?
my main covariate (additional treatment to patients) appears not to follow the
proportional hazards assumption, its effect being observed after one year of
Dear R users,

dependent covariates ?
my main covariate (additional treatment to patients) violates the proportional
hazards assumption, its effect being observed
after one year of treatment but not before (this
