simdata

This simulated data contains event times that are left censored, right
censored, interval censored, or non-censored (observed event). The data is
generated from a stratified Weibull distribution model in which each stratum
is assumed to have an independent stratum-specific shape parameter. In
addition, the regression coefficients corresponding to the vector of
explanatory variables excluding the stratum indicator are assumed to be
constant across strata.

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.
