Comparación de intervalos de confianza para la función de supervivencia con censura a derecha

this work compares methods to find confidence interval for the survival function such as the resampling methods bootstrap, applied to the kaplan-meier and nelson-aalen estimators. also through \log, \log(-\log) and arcsin transformations that can result more effectives in many cases. the behavior of nonparametric confidence intervals against parametric ones is also shown.
