create_event_dist {psborrow2}

Specify a Time to Event Distribution

Description

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)
