Compute Owen-like Function TOwen1(h, a)

TOwen1.Rd

TOwen1 computes an Owen's \(T\)-function variant (or a related special function) for vectors h and a based on the tha function in https://people.sc.fsu.edu/~jburkardt/c_src/owen/owen.html. Non-finite inputs in h or a yield NA at the corresponding positions.

Usage

TOwen1(h, a, threads = 1)

Arguments

threads

integer. Number of threads to request from the C implementation (if supported). Default is 1.

Value

A numeric vector of length length(h) with the computed values. Elements where either h or a is non-finite are NA. The returned vector is given class "snreg" for downstream compatibility.

Details

Owen's T Function Variant via C Backend

This is a thin R wrapper around a native routine with signature:


  void TOwen1(int *n, double *h, double *a, double *out, int *threads)

Examples

if (FALSE) { # \dontrun{
  library(snreg)

  # Basic usage. Vectorized 'a':
  h <- c(-1, 0, 1, 2)
  a <- 0.3
  TOwen1(h, a)

  # Vectorized 'a' with non-finite entries:
  a2 <- c(0.2, NA, 1, Inf)
  TOwen1(h, a2)
} # }
