Testing mean-variance efficiency in CAPM with possibly non-gaussian errors : an exact simulation-based approach
Beaulieu, Marie-Claude; Dufour, Jean-Marie; Khalaf, Lynda - 2003
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. These tests are developed in the framework of...

The performance of panel cointegration methods : results from a large scale simulation study
Wagner, Martin; Hlouskova, Jaroslava - 2007
This paper presents results concerning the performance of both single equation and system panel cointegration tests and estimators. The study considers the tests developed in Pedroni (1999, 2004), Westerlund (2005), Larsson, Lyhagen, and Löthgren (2001) and Breitung (2005); and the estimators...

Alternative measures of the explanatory power of multivariate probit models with continuous or ordinal responses
Spieß, Martin; Tutz, Gerhard - 2002
In this paper R2-type measures of the explanatory power of multivariate linear and categorical probit models proposed in the literature are reviewed and their deficiencies are discussed. It is argued that a measure of the explanatory power should take into account the components which are...

Testing for Poverty Dominance : An Application to Canada
Chen, Wen-Hao - 2018
The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty ranking across...

Fixed and long time span jump tests : new Monte Carlo and empirical evidence
Cheng, Mingmian; Swanson, Norman R. - In: Econometrics : open access journal 7 (2019) 1/13, pp. 1-32
Numerous tests designed to detect realized jumps over a fixed time span have been proposed and extensively studied in the financial econometrics literature. These tests differ from “long time span tests” that detect jumps by examining the magnitude of the jump intensity parameter in the data...
