We used Cox – Regression model as the best model to analysis data, we estimated model's parameter by using (Partial Likelihood) method, and then test the model's parameter by using (Wald Test), and the result shown that the variable (Treatment Type) has the significal effect on survival time. And we used (Likelihood Ratio Test), it was shown that the model which contains the variable (Treatment Type) is much more appropriate for the data of this research. | ||
