In nhppp: Simulating Nonhomogeneous Poisson Point Processes

Vectorized sampling from a zero-truncated non homogeneous Poisson Point Process (NHPPP) from an interval (thinning method) with piecewise constant_majorizers (R)

Description

Vectorized sampling from a zero-truncated non homogeneous Poisson Point Process (NHPPP) from an interval (thinning method) with piecewise constant_majorizers. The majorizers are step functions over equal-length time intevals.

Usage

vztdraw_intensity_step_regular(
  lambda = NULL,
  lambda_args = NULL,
  Lambda_maj_matrix = NULL,
  lambda_maj_matrix = NULL,
  rate_matrix_t_min = NULL,
  rate_matrix_t_max = NULL,
  t_min = NULL,
  t_max = NULL,
  atmost1 = FALSE,
  ...
)

Arguments

lambda	(function) intensity function, vectorized
lambda_args	(list) optional arguments to pass to lambda
Lambda_maj_matrix	(matrix) integrated intensity rates at the end of each interval
lambda_maj_matrix	(matrix) intensity rates, one per interval
rate_matrix_t_min	(scalar | vector | column matrix) is the lower bound of the time interval for each row of (Lambda|lambda)_maj_matrix. The length of this argument is the number of point processes that should be drawn.
rate_matrix_t_max	(scalar | vector | column matrix) the upper bound of the time interval for each row of (Lambda|lambda)_maj_matrix. The length of this argument is the number of point processes that should be drawn.
t_min	(scalar | vector | column matrix) is the lower bound of a subinterval of (rate_matrix_t_min, rate_matrix_t_max]. If set, times are sampled from the subinterval. If omitted, it is equivalent to rate_matrix_t_min.
t_max	(scalar | vector | column matrix) is the upper bound of a subinterval of (rate_matrix_t_min, rate_matrix_t_max]. If set, times are sampled from the subinterval. If omitted, it is equivalent to rate_matrix_t_max.
atmost1	boolean, draw at most 1 event time
