Calculating the probability of an event at time "t" from a Cox model fit
...robability of event at time (t) is
estimated for cox fit models, I want to estimate this probability on scoring
dataset score_data as below with covariate x1 and x2.
Is it possible/ is there any way to get these probabilities? since in
predictProb.coxph function it requires response, which is not preseent on
scoring sample.
n = 10000
set.seed(1)
x1 = rnorm(n,0)
x2 = rnorm(n,0)
score_data <- data.frame(x1,x2)
Thanks in advance!!

Interpretation of 'Intercept' in a 2-way factorial lm
Hi all,
I hope this question is not too trivial. I can't find an explanation
anywhere (Stats and R books, R-archives) so now I have to turn to the R-list.
Question:
If you have a factorial design with two factors (say A and B with two
levels each). What does the intercept coefficient with
treatment.contrasts represent??
Here is an example without interaction where A has two levels A1 and
