A new matrix statistic for the hausman endogeneity test under heteroskedasticity
Papadopoulos, Alecos - In: Econometrics : open access journal 11 (2023) 4, pp. 1-11
We derive a new matrix statistic for the Hausman test for endogeneity in cross-sectional Instrumental Variables … estimation, that incorporates heteroskedasticity in a natural way and does not use a generalized inverse. A Monte Carlo study … examines the performance of the statistic for different heteroskedasticity-robust variance estimators and different skedastic …

Testing mean-variance efficiency in CAPM with possibly non-gaussian errors: an exact simulation-based approach
Dufour, Jean-Marie; Beaulieu, Marie-Claude; 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...

Diagnostic tests for homoskedasticity in spatial cross-sectional or panel models
Baltagi, Badi H.; Pirotte, Alain; Yang, Zhenlin - 2020
We propose an Adjusted Quasi-Score (AQS) method for constructing tests for homoskedasticity in spatial econometric models. We first obtain an AQS function by adjusting the score-type function from the given model to achieve unbiasedness, and then develop an Outer-Product-of-Martingale-Difference...
