Finite-Sample Diagnostics for Multivariate Regressions with Applications to Linear Asset Pricing Models
DUFOUR, Jean-Marie; KHALAF, Lynda; BEAULIEU, Marie-Claude - Centre Interuniversitaire de Recherche en Économie … - 2003
In this paper, we propose several finite-sample specification tests for multivariate linear regressions (MLR) with applications to asset pricing models. We focus on departures from the assumption of i.i.d. errors assumption, at univariate and multivariate levels, with Gaussian and non-Gaussian...

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 Économie … - 2003
We study the problem of testing the error distribution in a multivariate linear regression (MLR) model. The tests are functions of appropriately standardized multivariate least squares residuals whose distribution is invariant to the unknown cross-equation error covariance matrix. Empirical...

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...
