BEKKs (version 1.4.6)

Multivariate Conditional Volatility Modelling and Forecasting

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) . For an overview, we refer the reader to Fülle et al. (2024) .
