In WARDEN: Workflows for Health Technology Assessments in R using Discrete EveNts

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

Description

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.

Details

Other arguments relevant to each function can be called directly

Value

A vector of time to event estimates from the given parameters

Examples

draw_tte(n_chosen=1,dist='exp',coef1=1,beta_tx=1)
draw_tte(n_chosen=10,"poisgamma",coef1=1,coef2=1,obs_time=1,return_ind_rate=FALSE)
