Nothing
The main function is icweib, which fits a stratified Weibull proportional hazards model for left censored, right censored, interval censored, and noncensored survival data. We parameterize the Weibull regression model so that it allows a stratumspecific baseline hazard function, but where the effects of other covariates are assumed to be constant across strata.
