Bayesiansk Dynamisk Betinget Korrelations-GARCH (Bayesiansk DCC-GARCH)

Bayesiansk DCC-GARCH estimerer tidsvarierende korrelationer på tværs af flere finansielle eller økonomiske serier ved at kombinere Engle's DCC-GARCH-struktur med Bayesiansk inferens. I stedet for at maksimere en likelihood, placerer den prior-fordelinger over alle parametre og anvender Markov Chain Monte Carlo (MCMC) sampling til at producere fulde posterior-fordelinger, hvilket giver rigere usikkerhedskvantificering end klassisk DCC-GARCH.
