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 ...
Exact Nonparametric Two-Sample Homogeneity Tests for Possibly Discrete Distributions
(Université de Montréal. Département de sciences économiques., 2001)
In this paper, we study several tests for the equality of two unknown distributions. Two are based on empirical distribution functions, three others on nonparametric probability density estimates, and the last ones on ...
