• Resumen

  • In this talk, a new goodness-of-fit test for parametric regression models when the response variable is right censored will be presented. The test is based on the comparison of a parametric estimator and a nonparametric estimator of the distribution of the errors of the regression model.We propose Kolmogorov-Smirnov and Cramer-von Mises type statistics, and we use a bootstrap mechanism in order to approximate the critical values of the test. Some simulations and an application to real data will be shown.
