I am trying to obtain the confidence interval (CI) of median survival time using complex survey data (for both grouped and combined data). I have used the following estimate survival function svykm command but it only gives me the median value with no CI estimates.
s1<-svykm(formula = Surv(age, status) ~ time, design = design, ci=TRUE)
Any suggestions on how I can obtain the median survival time confidence intervals after running the above R command/syntax.
Or is there any R code, other suggestions or way to obtain the median survival time together with their respective confidence interval estimates for survey data
