- AB In this paper we discuss the non-parametric estimation of a distribution
- function based on incomplete data for which the measurement origin of a
- survival time or the date of enrollment in a study is known only to
- belong to an interval. Also the survival time of interest itself is
- observed from a truncated distribution and is known only to lie in an
- interval. To estimate the distribution function, a simple
- self-consistency algorithm, a generalization of Turnbull's (1976,
- Journal of the Royal Statistical Association, Series B 38, 290-295)
- self-consistency algorithm, is proposed. This method is then used to
- analyze two AIDS cohort studies, for which direct use of the EM
- algorithm (Dempster, Laird and Rubin, 1976, Journal of the Royal
- Statistical Association, Series B 39, 1-38), which is computationally
- complicated, has previously been the usual method of the analysis.
