nhppp (version 1.0.2)

ztdraw_intensity: 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
)

Value

a vector of at least 1 event times

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
