Structural Break Tests Robust to Regression Misspecification
Econometrics, 2018 Structural break tests for regression models are sensitive to model misspecification. We show—analytically and through simulations—that the sup Wald test for breaks in the conditional mean and variance of a time series process exhibits severe

A Pretest to Differentiate Between Weak and Nearly-Weak Instrument Asymptotics [PDF]
We propose a pretest, bootstrap Kolmogorov-Smirnov test, to differentiate between weak and nearly-weak asymptotics. This is based on bootstrapping Wald Continuous Updating Estimator (CUE) based test.

Multivariate tests of asset pricing: Simulation evidence from an emerging market [PDF]
The finite sample performance of the Wald, GMM and Likelihood Ratio (LR) tests of multivariate asset pricing tests have been investigated in several studies on the US financial markets. This paper extends this analysis in two important ways.

Describing randomization in trials included in systematic reviews in orthopaedic surgery
Bone & Joint OpenAims: Systematic reviews of randomized controlled trials (RCTs) are the highest level of evidence used to inform patient care. However, it has been suggested that the quality of randomization in RCTs in orthopaedic surgery may be low. This study aims to

On the Uniqueness of Wald Sequential Tests
The Annals of Mathematical Statistics, 1956 Under certain mild restrictions on the distributions involved, it is shown that the probabilities of the two types of error uniquely determine the two bounds characterizing the Wald sequential probability ratio test.
