Subject: st: sample size calculation for survival data
Dear all,
Could somebody help me to get to know how one could calculate a sample size from
an existing medical records database. I would like to carry out a retrospective
study on clinical data collected for HIV/AIDS clients. I am estimating
mortality. How could I go about it?
Thank you
Kenneth
