Title: Recent Results on the Analysis of Current Status Data
Author(s): Nicholas P. Jewell*+

Address: Division of Biostatistics, Berkeley, CA, 94720-0001,
Keywords: current status data ; survival analysis ; double censoring ; competing risks ; case-control sampling ; nonparametrics
Abstract:

Researchers working with survival data are by now adept at handling issues associated with incomplete data, particular those associated with various forms of censoring. An extreme form of interval censoring, known as current status observation, refers to situations where the only available information on a survival random variable T is whether or not T exceeds a random independent monitoring time C. Doubly censored current status data has the added complication that both the origin and endpoint associated with T are interval-censored. This talk will introduce some recent developments and applications of current status to allow for response-based sampling and competing risks, and discussion extensions of these ideas to doubly censored current status data. Our remarks will be focused on nonparametric techniques where the form of the distribution function, or survival curve, associated with T, is left unspecified. Some examples where these methods have been applied will be used for illustration.
