Doubly interval-censored data
Have you looked at library(survival)? Unless I misunderstand what you
want, it should be there. Further documentation is provided in Venables
and Ripley (2002) Modern Applied Statistics with W, Therneau and
Grambsch (2000) Modeling Survival Data, Harrell (2001) Regression
Modeling Strategies (all Springer), and in materials downloadable from
www.r-project.org; see especially search -> "R site search". Have you
tried these sources?
hope this helps. spencer graves

Does anyone know of the existence of R code for estimating the survivor function and its standard error where survival time (T) is defined as the time between two interval-censored events, i.e., both events are only known to occur within an interval? This is the situation that commonly arises in longitudinal studies of viral infections. For instance T could be the time of clearing HPV infection when the dates of acquisition and loss (clearance) of infection are not measured exactly but known to occur between two consecutive dates (dates of prescheduled follow-up visits). Many thanks, Salah
