Borsa Istanbul Review, 2019 We study the volatility connectedness of stock market prices over various time horizons. We adopt a novel combination of copula and the asymmetric GARCH function (EGARCH) to fit this type of joint distribution consisting of the marginal distribution and ...

Correlation dynamics between Asia-Pacific, EU and US stock returns [PDF]
This paper investigates the correlation dynamics in the equity markets of 13 Asia-Pacific countries, Europe and the US using the asymmetric dynamic conditional correlation GARCH model (AG-DCC-GARCH) introduced by Cappiello, Engle and Sheppard (2006).

Global Risk Evolution and Diversification: a Copula-DCC-GARCH Model Approach
Revista Brasileira de Finanças, 2012 In this paper we estimate a dynamic portfolio composed by the U.S., German, British, Brazilian, Hong Kong and Australian markets, the period considered started on September 2001 and finished in September 2011. We ran the Copula-DCC-GARCH model on the daily returns conditional covariance matrix.

Equity market interdependence: the relationship between European and US stock markets. [PDF]
In this article, the degree of interdependence between European and US stock markets is measured by the conditional correlation between stock returns: the correlation coefficient is estimated using a model describing the variations over time in a number ...

A general multivariate threshold GARCH model with dynamic conditional correlations [PDF]
We propose a new multivariate GARCH model with Dynamic Conditional Correlations that extends previous models by admitting multivariate thresholds in conditional volatilities and correlations.

DCC-GARCH modeller med ulike avhengighetsstrukturer
, 2013 Hovedfokuset i denne oppgaven er å finne gode metoder for modellering av volatilitet og avhengighetsstruktur i finansielle porteføljer. En spesifikk multivariat GARCH modell, Dynamic Conditional Correlation (DCC-) GARCH, kombineres med copulaer og par-copula-konstruksjoner for å få en mer fleksibel modell til å modellere nettopp dette.

Consistent ranking of multivariate volatility models [PDF]
A large number of parameterizations have been proposed to model conditional variance dynamics in a multivariate framework. This paper examines the ranking of multivariate volatility models in terms of their ability to forecast out-of-sample conditional ...

Aperture NeuroAlzheimer's disease (AD) has a prolonged latent phase. Sensitive biomarkers of amyloid beta ($A\beta$), in the absence of clinical symptoms, offer opportunities for early detection and identification of patients at risk. Current $A\beta$ biomarkers, such
