Abstract
For establishing equivalence of survival functions of HIV/ AIDS data, log-rank test, the confidence interval procedure and Cox model procedure which are based on proportionality assumption were employed. Since proportionality assumption may not hold in some cases, attempt is made to develop a general procedure for testing the equivalence of survival time by a simple modification of Cox model.
