hess_loglik.likelihood_model: Default method to compute the hessian of the log-likelihood.

In likelihood.model: Likelihood-Based Statistical Inference in the Fisherian Tradition

Default method to compute the hessian of the log-likelihood.

Description

In case a hess_loglik method is not provided, this function will be used. It computes the hessian of the log-likelihood function using numerical differentiation.

Usage

## S3 method for class 'likelihood_model'
hess_loglik(model, control = list(), ...)

Arguments

model	The likelihood model
control	Custom arguments to pass to numDeriv::hessian.
...	Additional arguments (to pass into loglik)

Value

A function(df, par, ...) that computes the Hessian matrix of the log-likelihood evaluated at par given data df.
