R Documentation

Generic function for simulating from zero-truncated NHPPPs given the intensity function.

Description

Sample from zero-truncated NHPPP given the intensity function This is a wrapper to the package's specific functions, and thus somewhat slower. For time-intensive simulations prefer one of the specific functions.

Usage

ztdraw_intensity(
  lambda,
  line_majorizer_intercept = NULL,
  line_majorizer_slope = NULL,
  line_majorizer_is_loglinear = FALSE,
  step_majorizer_vector = NULL,
  t_min = NULL,
  t_max = NULL,
  atmost1 = FALSE
)

Arguments

`lambda`	(function) the instantaneous rate
`line_majorizer_intercept`	The intercept `alpha` of the loglinear majorizer function: `alpha + beta * t` or `exp(alpha + beta * t)`
`line_majorizer_slope`	The slope `beta` of the loglinear majorizer function: `alpha + beta * t` or `exp(alpha + beta * t)`
`line_majorizer_is_loglinear`	(boolean) if `TRUE` the majorizer is loglinear `exp(alpha + beta * t)`; if `FALSE` it is a linear function
`step_majorizer_vector`	(vector, double) `K` constant majorizing rates, one per interval; all intervals are of equal length (regular)
`t_min`	(double) the lower bound of the interval
`t_max`	(double) the upper bound of the interval
`atmost1`	boolean, draw at most 1 event time
