The Geometry of the Wald Test [PDF]

, 1990
The issue of the non-invariance of the Wald test under nonlinear reparametrisations of the restrictions under test is studied from a differential geometric viewpoint. Quantities that can be defined in purely geometrical terms are by construction invariant under reparametrisation, and various attempts are made to construct a Wald test out of such ...

A Wald test on the problem of homogeneity of variances

Communications in Statistics - Simulation and Computation, 2023
In this article, we propose a Wald test for homogeneity of variance in several normal distributions. The Wald test is an asymptotic test, and it is known that asymptotic tests perform well in large sample sizes, but not in small sample sizes. For this reason, we modified this test using a parametric bootstrap method called the computational approach ...

A Correction for Local Biasedness of the Wald and Null Wald Tests

Oxford Bulletin of Economics and Statistics, 1999
This paper proposes a procedure to overcome the problem of small‐sample local biasedness of the Wald test of a single restriction. The new test procedure involves finding two critical values, in order to obtain the desired size and local unbiasedness.
