Exact skewness-kurtosis tests for multivariate normality and goodness-of-fit in multivariate regressions with application to asset pricing models
Dufour, Jean-Marie; Khalaf, Lynda; Beaulieu, Marie-Claude - Centre Interuniversitaire de Recherche en Analyse des … - 2003
Dans cet article, nous proposons des tests sur la forme de la distribution des erreurs dans un modèle de régression linéaire multivarié (RLM). Les tests que nous développons sont fonction des résidus obtenus par moindres carrés multivariés, lesquels sont standardisés de façon à ce que...

Measuring High-Frequency Causality Between Returns, Realized Volatility and Implied Volatility
Dufour, Jean-Marie; Garcia, René; Taamouti, Abderrahim - Centre Interuniversitaire de Recherche en Analyse des … - 2011
In this paper, we provide evidence on two alternative mechanisms of interaction between returns and volatilities: the leverage effect and the volatility feedback effect. We stress the importance of distinguishing between realized volatility and implied volatility, and find that implied...
