En este trabajo se comparan métodos para encontrar intervalos de confianza para la función de supervivencia, como los métodos de remuestreo Bootstrap aplicado a los estimadores de Kaplan-Meier y Nelson-Aalen. También, mediante las transformaciones log, log(−log) y arc sen que pueden resultar en muchos casos más efectivos. Además, se muestra el comportamiento que presentan los intervalos de confianza no paramétricos frente a los paramétricos.
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.
