Pure-C++ log-likelihood for the xsdm model (math-scale parameters)

loglik_math_cpp.Rd

Computes the log-likelihood directly in C++ without any R callback in the inner loop. Semantically equivalent to the R function loglik_math.

Usage

loglik_math_cpp(
  param_vector,
  env_dat,
  occ,
  mask = NULL,
  negative = TRUE,
  num_threads = 0L
)

Arguments

param_vector

Named numeric vector of math-scale parameters. When `mask` is NULL, must contain every canonical name for the dimension p implied by `env_dat`. When `mask` is supplied, contains only the free (non-masked) parameters.

env_dat

3D numeric array with dimensions (n_loc, ts_length, p). No missing values allowed.

occ

Integer or logical vector of length n_loc, 0/1 or FALSE/TRUE.

mask

Optional named numeric vector of fixed parameters.

negative

Logical; if TRUE (default) returns the negative log-likelihood (the value to be minimized).

num_threads

Integer; 0 leaves the RcppParallel default.

Value

A scalar double.
