In aghq: Adaptive Gauss Hermite Quadrature for Bayesian Inference

Obtain the Hessian from an aghq object

Description

Quick helper method to retrieve the Hessian from an aghq object. Just calls aghq::get_opt_results.

Usage

get_hessian(obj, ...)

Arguments

obj	Object of class aghq returned by aghq::aghq.
...	Not used

Value

A numeric matrix of dimension dim(theta) x dim(theta) containing the negative Hessian of the log-posterior evaluated at the mode.
