In rbiogeme: Interface to 'Biogeme'

Check analytical derivatives against native finite differences

Description

This delegates to the public BIOGEME.check_derivatives() operation. The complete expression tree is compiled first; no R callback is evaluated by the derivative checker.

Usage

check_derivatives(
  model,
  model_name = "rbiogeme_model",
  controls = list(),
  control = NULL,
  verbose = FALSE
)

Arguments

model	A biogeme_model.
model_name	Native Biogeme model name.
controls	Named native Biogeme controls.
control	Optional biogeme_control() object; an alias for controls.
verbose	Whether native Biogeme should print the comparison.

Value

A list containing the native function value, analytical and finite difference gradients and Hessians, and their error vectors.
