simdata {straweib}

Simulated data with mixed types of events

Description

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.
