Exact Skewness-Kurtosis Tests for Multivariate Normality and Goodness-of-fit in Multivariate Regressions with Application to Asset Pricing Models
(Université de Montréal. Département de sciences économiques., 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 ...
Exact Multivariate Tests of Asset Pricing Models with Stable Asymmetric Distributions
(Université de Montréal. Département de sciences économiques., 2005)
In this paper, we propose exact inference procedures for asset pricing models that can be formulated in the framework of a multivariate linear regression (CAPM), allowing for stable error distributions. The normality ...
Simulation-Based Finite-Sample Tests for Heteroskedasticity and ARCH Effects
(Université de Montréal. Département de sciences économiques., 2001)
A wide range of tests for heteroskedasticity have been proposed in the econometric and statistics literature. Although a few exact homoskedasticity tests are available, the commonly employed procedures are quite generally ...
