tooth24

This data set contains data from the Signal Tandmobiel study, which is
described in the paper by Gomez G and others (2009). The time to event
is interval censored.

datasets

The main function is icweib(), which fits a stratified Weibull
proportional hazards model for left censored, right censored, interval censored,
and non-censored survival data. We parameterize the Weibull regression model
so that it allows a stratum-specific baseline hazard function, but where the
effects of other covariates are assumed to be constant across strata.
