Asymptotic Distribution of a Simple Linear Estimator for VARMA Models in Echelon Form
(Université de Montréal. Département de sciences économiques., 2005)
In this paper, we study the asymptotic distribution of a simple two-stage (Hannan-Rissanen-type) linear estimator for stationary invertible vector autoregressive moving average (VARMA) models in the echelon form representation. ...
Monte Carlo Tests with Nuisance Parameters: A General Approach to Finite-Sample Inference and Nonstandard Asymptotics
(Université de Montréal. Département de sciences économiques., 2005)
The technique of Monte Carlo (MC) tests [Dwass (1957), Barnard (1963)] provides an attractive method of building exact tests from statistics whose finite sample distribution is intractable but can be simulated (provided ...
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 ...
Finite-Sample Simulation-Based Inference in VAR Models with Applications to Order Selection and Causality Testing
(Université de Montréal. Département de sciences économiques., 2005)
Statistical tests in vector autoregressive (VAR) models are typically based on large-sample approximations, involving the use of asymptotic distributions or bootstrap techniques. After documenting that such methods can be ...
Logique et tests d'hypotheses: reflexions sur les problemes mal poses en econometrie
(Université de Montréal. Département de sciences économiques., 2001)
Dans ce texte, nous analysons les développements récents de l’économétrie à la lumière de la théorie des tests statistiques. Nous revoyons d’abord quelques principes fondamentaux de philosophie des sciences et de théorie ...
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 ...
Simulation-Based Finite and Large Sample Tests in Multivariate Regressions
(Université de Montréal. Département de sciences économiques., 2000)
In the context of multivariate linear regression (MLR) models, it is well known that commonly employed asymptotic test criteria are seriously biased towards overrejection. In this paper, we propose a general method for ...
Markovian Processes, Two-Sided Autoregressions and Finite-Sample Inference for Stationary and Nonstationary Autoregressive Processes
(Université de Montréal. Département de sciences économiques., 2000)
In this paper, we develop finite-sample inference procedures for stationary and nonstationary autoregressive (AR) models. The method is based on special properties of Markov processes and a split-sample technique. The ...
Économétrie, théorie des tests et philosophie des sciences
(Université de Montréal. Département de sciences économiques., 2000)
Dans ce texte, nous revoyons certains développements récents de l’économétrie qui peuvent être intéressants pour des chercheurs dans des domaines autres que l’économie et nous soulignons l’éclairage particulier que ...
Exact Tests for Contemporaneous Correlation of Disturbances in Seemingly Unrelated Regressions
(Université de Montréal. Département de sciences économiques., 2000)
This paper proposes finite-sample procedures for testing the SURE specification in multi-equation regression models, i.e. whether the disturbances in different equations are contemporaneously uncorrelated or not. We apply ...
