\title{Get (estimated) auxiliary (additional) parameters of the likelihood}
\usage{
get_aux_pars(gp_model, std_err = FALSE)
}
\arguments{
\item{gp_model}{A \code{GPModel}}

\item{std_err}{A \code{boolean}. If TRUE, (approximate) standard errors are calculated 
(= square root of diagonal of the inverse Fisher information for Gaussian likelihoods and 
square root of diagonal of a numerically approximated inverse Hessian for non-Gaussian likelihoods)}
}
\description{
Get (estimated) auxiliary (additional) parameters of the likelihood such as the shape parameter of a gamma or
a negative binomial distribution. Some likelihoods (e.g., bernoulli_logit or poisson) have no auxiliary parameters
}
\examples{
\donttest{
data(GPBoost_data, package = "gpboost")
X1 <- cbind(rep(1,dim(X)[1]),X) # Add intercept column
y_pos <- exp(y)
gp_model <- fitGPModel(group_data = group_data[,1], y = y_pos, X = X1, likelihood="gamma")
get_aux_pars(gp_model)
