Effect of Informative Censoring on the Power of Some Log-Rank Type Tests.
The survival analysis is a set of techniques for analyzing the elapsed time until the occurrence of an event of interest, also called lifetime, which can be completely or partially observed. In practice, a common problem is to compare the survival experiences of at least two groups...

En la práctica, un problema frecuente consiste en comparar las experiencias de supervivencia de al menos dos grupos bajo estudio. La estrategia de análisis más común consiste en usar pruebas Log-Rank, pero estas no distinguen si el mecanismo de censura es informativo o no. En este trabajo se evaluó, bajo diferentes escenarios de simulación, la potencia estimada de algunas pruebas Log-Rank cuando los datos presentan censura informativa.
