Specify a Time to Event Distribution — create_event

Uses simsurv::simsurv to generate time to event data. See simsurv help for more details.

Usage

create_event_dist(
  dist = NULL,
  lambdas = NULL,
  gammas = NULL,
  mixture = FALSE,
  pmix = 0.5,
  hazard = NULL,
  loghazard = NULL,
  cumhazard = NULL,
  logcumhazard = NULL,
  ...
)

null_event_dist()

Arguments

dist: Specify the distribution "exponential"
lambdas: Scale parameter
gammas: Second parameter needed for Weibull or Gompertz distributions
mixture: Use mixture model?
pmix: Proportion of mixtures
hazard: A user defined hazard function
loghazard: Alternatively, a user defined log hazard function
cumhazard: Alternatively, a user defined cumulative hazard function
logcumhazard: Alternatively, a user defined log cumulative hazard function
...: Other simsurv parameters

Value

A SimDataEvent object

null_event_dist returns an object with no parameters specified that does not simulate event times.

Examples

weibull_surv <- create_event_dist(dist = "weibull", lambdas = 1 / 200, gammas = 1)
exp_event_dist <- create_event_dist(dist = "exponential", lambdas = 1 / 36)
null_event_dist()
#> An object of class "DataSimEvent"
#> Slot "params":
#> list()
#> 
#> Slot "label":
#> [1] "No distribution specified"
