Testing exogeneity under distributional misspecification [PDF]
We propose a general test for exogeneity that is robust against distributional misspecification. The test can also be used to identify other types of misspecifications, such as the presence of a random coefficient.

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Nonlinear Cointegration, Misspecification and Bimodality [PDF]
We show that the asymptotic distribution of the ordinary least squares estimator in a cointegration regression may be bimodal. A simple case arises when the intercept is erroneously omitted from the estimated model or in nonlinear-in-variables models ...

Journal of Policy Analysis and Management, EarlyView.Abstract Researchers and policymakers assert competing behavioral models of polluters. One model portrays polluters as best approximated by the perfectly informed, rational actor from economics textbooks. Another model portrays polluters, particularly small and medium facilities, as imperfectly informed, cognitively bounded, pro‐social actors.

Detection of Functional Form Misspecification in Cointegrating Relations [PDF]
A simple specification test based on fully modified residuals and the CUSUM test for cointegration of Xiao and Phillips (Journal of Econometrics, 2002) are considered as means of testing for functional form in long-run cointegrating relations.

Dynamic Misspecification in Nonparametric Cointegrating Regression [PDF]
Linear cointegration is known to have the important property of invariance under temporal translation. The same property is shown not to apply for nonlinear cointegration.

Investigating item complexity as a source of cross-national DIF in TIMSS math and science
Large-scale Assessments in EducationBackground Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or ...

Psychology in the Schools, EarlyView.ABSTRACT This study applied multidimensional scaling (MDS) to the Cognitive Assessment System‐Second Edition (CAS2) to investigate the structural validity of PASS theory (Planning, Attention, Simultaneous, Successive) across two age groups (5−7, 8−18 years) in the normative sample (N = 1342).

Advances in Mechanical Engineering, 2017 Among the ways to construct experimental designs having been proposed, orthogonal design, uniform design, and D-efficient design are state-of-the-art methods. This article provides detailed comparisons on the efficiency and robustness among these methods

PLANTS, PEOPLE, PLANET, EarlyView.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.
