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

Draw time to event (tte) from a Poisson or Poisson-Gamma (PG) Mixture/Negative Binomial (NB) Process using C++

Description

Draw time to event (tte) from a Poisson or Poisson-Gamma (PG) Mixture/Negative Binomial (NB) Process using C++

Usage

rpoisgamma_rcpp(
  n,
  rate,
  theta = NULL,
  obs_time = 1,
  t_reps = NULL,
  seed = NULL,
  return_ind_rate = FALSE,
  return_df = FALSE
)

Arguments

n	The number of observations to be drawn
rate	rate of the event (events per unit time)
theta	Optional. If provided, Poisson-Gamma (NB). Represents gamma shape.
obs_time	period over which events are observable
t_reps	Optional. Number of TBEs to be generated to capture events within the observation window.
seed	Optional integer seed for reproducibility.
return_ind_rate	Logical: include individual rate vector in output when theta provided.
return_df	Logical: return a data.frame with event-level rows (if TRUE).

Value

If return_df=TRUE: a data.frame (or NULL if no events). Else: list with tte and optionally ind_rate.

Examples

rpoisgamma_rcpp(1, rate = 1, obs_time = 1, theta = 1)
