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

Generalized inverses and asymptotic properties of Wald tests [PDF]
Economics Letters, 1987 We consider Wald tests based on consistent estimators of g-inverses of the asymptotic covariance matrix ∑ of a statistic that is n^1/2-asymptotically normal distributed under the null hypothesis. Under the null hypothesis and under any sequence of local alternatives in the column space of ∑, these tests are asymptotically equivalent for any choice of g-

Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration
Advanced Science, EarlyView.This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

Verfahrensdokumentation für IMEB-A: Instrument for Measuring Epistemic Beliefs in Accounting
, 2018 Das IMEB-A ist ein standardisierter Fragebogen zur Erfassung individueller Vorstellungen über Wissen und Wissenserwerb im Rechnungswesen. Es baut auf dem Modell epistemischer Überzeugungen von Hofer und Pintrich (1997) sowie Berding (2015, 2016b, 2017 ...

Advanced Science, EarlyView.Large‐scale UK Biobank analyses identify clinical and proteomic signatures for early prediction of valvular heart disease and its subtypes. Proteins add predictive value for VHD, AVS, and MVR, with outcome‐specific compact panels showing translational potential. Multi‐layer evidence highlights matrix remodeling, protease regulation, immune inflammation,

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

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Rice is the main staple food for more than half of the world's population and the income from rice is an essential source for livelihoods of millions of households. We examine whether direct seed in rice production is an adaptation of rice farmers to rainfall changes and farm labor scarcity.

Heteroskedasticity Testing Through Comparison of Wald-Type Statistics [PDF]
A test for heteroskedasticity within the context of classical linear regression can be based on the difference between Wald statistics in heteroskedasticity-robust and nonrobust forms.
