Rd. Gill et al., INEFFICIENT ESTIMATORS OF THE BIVARIATE SURVIVAL FUNCTION FOR 3 MODELS, Annales de l'I.H.P. Probabilites et statistiques, 31(3), 1995, pp. 545-597
Three explicit estimators-of the bivariate survival functions for thre
e types of data are analyzed by proving the analytical and probabilist
ic conditions necessary for application of the functional delta-method
. It tells us that the estimators converge weakly at root n-rate to a
Gaussian process and that for estimation of their asymptotical distrib
ution the bootstrap works well. We also prove efficiency of the Dabrow
ska and Prentice-Cai estimator for the bivariate censoring model under
independence.
