WebbIn the standard simstudy data generation process for survival/time-to-event outcomes that includes covariates that effect the hazard rate at various time points, the ratio of hazards comparing different levels of a covariate are constant across all time points. For example, if we have a single binary covariate x, the hazard λ ( t) at time t is Webb2 nov. 2024 · Simulates data sets in order to explore modeling techniques or better understand data generating processes.

First, the user defines the data elements of a data set either in an external csv file or internally through a set of repeated definition statements. Second, the user generates the data, using these definitions. raymond walters

"Webb8 feb. 2024 · The package simstudy has some functions that facilitate generating survival data using an underlying Weibull distribution. Originally, I added this to the package because I thought it would be interesting to try to do, and I figured it would be useful for me someday (and hopefully some others, as well).
