Choosing the best method Estimation of Survival Function for breast cancer patients

Abstract

The analysis of the data using the survival function is one of the most important topics in our daily life because it is included in many medical fields where cancer data were collected from the center of the Middle Euphrates in Najaf. The data studied were for the period (2013-2016), and the total number of patients in the study was (96) and all of them died during this period but on different dates . A number of methods were used to estimate the survival function, The methods used are (the Kernel method, the Nelson Method (NL) method, the Empirical Method (EM) method). The researcher then compared the methods of estimating the survival function and that which calculated from the data to choose the best of these methods depending on the average of the mean squares error (MSE) .
