Title: Nonparametric estimation of the conditional survival function for ordered multivariate failure time data
Authors: Luis Machado - University of Minho (Portugal) [presenting]
Abstract: In longitudinal studies of disease, patients may experience several events through a follow-up period. In these studies, the sequentially ordered events are often of interest and lead to problems that have received much attention recently. Issues of interest include the estimation of bivariate survival, marginal distributions and the conditional distribution of gap times. We consider the estimation of the survival function conditional to a previous event. Different nonparametric approaches will be considered for estimating these quantities, all based on the Kaplan-Meier estimator of the survival function. We explore the finite sample behavior of the estimators through simulations. Real data illustration based on a German breasts cancer study is included.
