In public health research, it is typical to examine survival data using basic statistical approaches, which are discussed in this work. It is impossible to analyse the data using the standard way because of the censoring.Since the rise of personal computers and statistical computing, nonparametric techniques have become more popular than parametric ones. The first had less restrictions. Because of these assumptions, it is possible to get estimates with fewer standard errors and a better understanding of the data
