Wald Criteria for Jointly Testing Equality and Inequality Restrictions
Econometrica, 1986We propose a large sample Wald test for sets of equality and inequality constraints on the parameters of a model. The null or the alternative hypothesis may be subject to inequality constraints. The computation of the test statistic is relatively simple.

On A. Wald’s Test Comparing Two Normal Samples
Theory of Probability & Its Applications, 1964The well known Wald test comparing the means of two normal samples with unequal variances is of the form: $|{{\bar x - \bar y} / {s_2 }}| \geqq \varphi ({{s_1 } / {s_2 }})$ (critical zone). A. Wald constructed the function $\varphi $ for which the test is approximately similar with respect to $\sigma _1 $ and $\sigma _2 $.

Nous presentons dans ce chapitre des exemples de tests de Wald, ainsi que les tests de Student et le test de Welch. Ce sont des tests sur la valeur d’un parametre, ou l’on pourra appliquer les principes vus dans le chapitre precedent.

Strategical Test — A Generalization of the Wald’s Sequential Test
1983It is well known that the Wald’s sequential test terminates with probability one (and simultaneously is in some sense optimal) if a sampled sequence of random variables is independent and identically distributed (i.i.d.). In this paper we shall deal with the Wald’s sequential test constructed for a special sequence of dependent and unidentically ...
