Weibull survival modeling with covariate
...vival analysis can help me with
the following.
I would like to fit a Weibull curve,
that may be dependent on a covariate,
my dataframe "labdata" that has the
fields "cov", "time", and "censor". Do
I do the following?
wieb<-survreg(Surv(labdata$time,
labadata$censor)~labdata$cov,
dist="weibull")
This returns:
> weib
Call:
survreg(formula = Surv(labdata$time,
labdata$censor) ~ labdata$cov,
dist = "weibull")
Coefficients:
(Intercept) labdata$cov
