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 ...

Coincidence of the Rao Test, Wald Test, and GLRT in Partially Homogeneous Environment

IEEE Signal Processing Letters, 2008
This letter deals with the problem of detecting a signal known up to a scaling factor in the presence of partially homogeneous Gaussian disturbance with unknown covariance matrix. It is proved that the Rao test and the Wald test coincide with the generalized likelihood ratio test (GLRT) previously derived. Otherwise stated, the Rao test, the Wald test,

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.

On the Use of Wald's Test in Exponential Families

International Statistical Review / Revue Internationale de Statistique, 1985
The paper investigates the behaviour of Wald's test (the maximum likelihood test statistic) when applied to hypothesis testing in one- parameter exponential families for one-sample problems. Conditions under which Wald's test is well behaved and conditions under which Wald's test may be misleading are derived, the main conclusion being that in general ...
