**Title:** Nonparametric estimation for cross-sectional data

**Abstract:** Current duration data collected from cross-sectional sampling provides an alternative opportunity to estimate the survival function of the variable of interest in addition to prospective and retrospective designs. In this talk, we will first review the connection of current duration data with shape-constrained inference. While different nonparametric estimators for the underlying survival function have been proposed in the literature, some of their theoretical properties are missing. We will establish the asymptotic distributions of these estimators. Semiparametric models will also be discussed.
