[Solved] Survival analysis [closed]


This should solve your problem:

mod <- survreg((Surv(as.numeric(Time), event=Status)) ~ Prison+Dose+Clinic,
            data = meth, 
            dist = "lognormal")

as you reported to me that:

names(meth)
# [1] "ID" "Clinic" "Status" "Time" "Prison" "Dose"

Note, it is Time, not time; Also, it is Status, not status. In fact, all variables names start with a capital letter!
