I'm trying to obtain the median time to failure using stci, p(50). But it will
not work if I first stset the data using any kind of weights. stci, median
will not work either if I stset the data using weights. I suspect the problem
has to do with weighted data not being allowed in the calculation of the
standard error (to obtain the confidence interval for the median). Now I don't
need the confidence interval, so I'd be glad if someone could let me know how
I can simply get the median.
Thanks so much!
