rpoisgamma_rcpp: 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
)

Value

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

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).

Examples

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