\arguments{
\item{object}{A fitted \code{xreg2} object.}

\item{k}{Numeric; penalty per parameter. Default \code{2}.}

\item{just_total}{Logical; return only the total AIC across all components.
Default \code{TRUE}.}

\description{
Computes the Akaike Information Criterion for a fitted
  \code{xreg2} model. Scale parameters (SIGMA, LN_SIGMA, OMEGA, LN_OMEGA)
  are excluded from the parameter count.
