%description
Methods and tools for estimating, simulating and forecasting of so-called
BEKK-models (named after Baba, Engle, Kraft and Kroner) based on the fast
Berndt–Hall–Hall–Hausman (BHHH) algorithm described in Hafner and Herwartz
(2008) <doi:10.1007/s00184-007-0130-y>. For an overview, we refer the
reader to Fülle et al. (2024) <doi:10.18637/jss.v111.i04>.
