Abstract: This paper discussed the analysis of multivariate of time to even (TTE) or survival-time data.It introduces the principle of PWpmodel and the applied technique of PWpmodel in dealing with the actual multivariate survival-time data.The results show that this method is good at dealing with multivariate outcome event, and it can obtain the effect of concomitant variable to the different outcome events to limit the parametric value of the model.PWpmodel is an efficient analytical method for dealing with multivariate survival-time data.

Key words: multivariate survival-time data, PWpmodel, multivariate proportional hazard model
