In this paper, we investigate cross-correlations between nonferrousmetal spot and futures markets using detrended cross-correlation analysis (DCCA). We find the existence of significant cross-correlations for both return and volatility series. The DCCA-based crosscorrelation coefficients are very high and decrease with the futures maturity increases. Using the multifractal extension of DCCA, th...

Volatility spillovers: A sparse multivariate GARCH approach with an application to commodity markets
We propose sparse DCC-GARCH and BEKK-GARCH models based on L 1 ${L}_{1}$ regularization. use the to study daily return volatility correlation spillovers for 24 constituents of Bloomberg commodity index in period 2000–2018. The outperform diagonal out-of-sample terms model fit other criteria. also test whether higher visibility metals energy markets compared with agricultural commodities affects...
abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...
