Dear list,
I have a question
I have match using full match optional, this return also weights and subclass variables.
Must i in coxph function from survival package use also weights:
Coxph (....... ~ a + strata(subclass), weights= weights, data) or
Coxph (....... ~ a + strata(subclass), data) or
Coxph (....... ~ a , weights= weights, data)
Thanks in advance
Sorry for noise

Hello,
I have a question regarding nearest matching method. my function is as
follows: m.out <- matchit(treat ~ SEX + ETHN + EDUC + log_VL_BL + CD4_BL +
Dur_HIV + hepC + hepB + IVD, data = mydata, method= "nearest")
Dur_HIV is the duration og HIV infection of a patient. How is a 1:1
matching done? I do not have 2 patients with the same duration of HIV
infection in days. Does it take the nearest duration? Also is the algorithm
atching 1:1 per variable or for all the variables?
Thanks,
Susan
