Can -stcox-* do multilevel analyses with one failure?

[Roberto Bakker]

Hi everybody,

Can -stcox- do multilevel analyses with one failure?; i.e., can -stcox- take the repeated covariate measures into the analyses (multilevel) or can -stcox- only take one wave of covariate measures?
Lets say, the failure is death; the covariates are temperature and medication, which are repeatedly measured; so I have repeated measures (panel) data and want to take covariate-measures from all waves.
I hope I am clear. Thank you in advance.

ID	enter	death	temp	medication
1	1	0	38.0	antibiotic A
1	2	1	37.5	antibiotic B
2	1	0	36.5	non
2	2	0	37.9	antibiotic A
2	3	1	39.0	antibiotic C
3	1	0	37.2	non
3	2	0	37.3	non
3	3	0	38.1	non
3	4	1	39.0	non

Roberto:
you might be looking for a Cox model with shared frailty (see -shared()- option under -stcox-).

Carlo: thank you!

And cluster()? Is this also taking multilevel into account?

Roberto:
-cluster()- option for -stcox- can be wisely invoked whenever you suspect a
