several advantages compared to the linear correlation measure in modeling comovement. This paper introduces a copula ARMA-GARCH … model for analyzing the comovement of indexes in German equity markets. The model is implemented with an ARMA-GARCH model … skewed Student's t copula ARMA(1,1)-GARCH(1,1) model with Lévy fractional stable noise is superior to alternative models …

-Exponential Conditional Correlation (MECC) model. The paper applies the WDCC approach to the exponential GARCH (EGARCH) and GJR models to …

different GARCH models. …

principal index of the London Stock Exchange supports our model when compared to other frequently used GARCH-type models, which …

GARCH (1,1) model. As a result, the GARCH estimate tends to have too small a standard error relative to the true one when … the ARCH parameter is small, even when sample size becomes very large. In combination with an upward bias in the GARCH …

In this paper we test for (Generalized) AutoRegressive Conditional Heteroskedasticity [(G)ARCH] in daily and weekly … data on 22 exchange rates and 13 stock market indices using the standard Lagrange Multiplier [LM] test for GARCH and a new … result is that we find spurious GARCH in over 50% of the cases. Using Monte Carlo simulations, in which we evaluate our …

- Maximum Likelihood Estimator for a general nonlinear conditional mean model with first-order GARCH errors. …

ARMA(1,1)-GARCH(1,1) and ARMA(3,2)-GJR(1,1) models are suitable for modelling ENSO volatility. Moreover, 1998 is a turning …
