Finite-Sample Diagnostics for Multivariate Regressions with Applications to Linear Asset Pricing Models
(Université de Montréal. Département de sciences économiques., 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 ... -
Testing Mean-Variance Efficiency in CAPM with Possibly Non-Gaussian Errors : An Exact Simulation-Based Approach
(Université de Montréal. Département de sciences économiques., 2002)In this paper we propose exact likelihood-based mean-variance efficiency tests of the market portfolio in the context of Capital Asset Pricing Model (CAPM), allowing for a wide class of error distributions which include normality as a special case. ...
