Draw a time to event from a list of parametric survival functions

Usage

draw_tte(
  n_chosen,
  dist,
  coef1 = NULL,
  coef2 = NULL,
  coef3 = NULL,
  ...,
  beta_tx = 1,
  seed = NULL
)

Arguments

n_chosen: The number of observations to be drawn
dist: The distribution; takes values 'lnorm','norm','mvnorm','weibullPH','weibull','llogis','gompertz','gengamma','gamma','exp','beta','poisgamma'
coef1: First coefficient of the distribution, defined as in the coef() output on a flexsurvreg object (rate in "rpoisgamma")
coef2: Second coefficient of the distribution, defined as in the coef() output on a flexsurvreg object (theta in "rpoisgamma")
coef3: Third coefficient of the distribution, defined as in the coef() output on a flexsurvreg object (not used in "rpoisgamma")
...: Additional arguments to be used by the specific distribution (e.g., return_ind_rate if dist = "poisgamma")
beta_tx: Parameter in natural scale applied in addition to the scale/rate coefficient -e.g., a HR if used in an exponential- (not used in "rpoisgamma" nor "beta")
seed: An integer which will be used to set the seed for this draw.

Value

A vector of time to event estimates from the given parameters

Details

Other arguments relevant to each function can be called directly
