draw_tte: 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
)

Value

A vector of time to event estimates from the given parameters

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

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)
