Some Issues in Weak Local Independence in Item Response Theory
… of Pashley and Reese (in press) for simulating locally dependent data, whose item pair dependencies relate directly to local dependence assessment procedures is discussed. This method is extended to allow for the simulation of local dependence that varies in magnitude across the examinee ability …

Some issues in item response theory
… studied in this thesis are: the assumption of local independence (LI) in item response theory (IRT) models in the first three chapters, and differential item functioning (DIF) in IRT in the last chapter. A new term ""conditional trivariance"" for three items is defined, which is a measurement …

An Analysis of Non-Uniform Stress States in Finite Thin Film/substrate System: The Need of Full-Field Curvature Measurements
… and film thicknesses. They all feature a ""non-local"" dependence on curvatures, which make full-field measurement a necessity for the experimental inference of such stresses. We also extend the methodologies to the case that of single thin film/substrate subjected to non-uniform anisotropic …

Population genetics of species on the genera Tursiops and Delphinus within the Gulf of California and along the western coast of Baja California.
… and common dolphins supports the hypothesis of local habitat dependence and resource specialization at both the population and putative species level. Fine-geographic scale structure was detected in coastal bottlenose dolphins, which seemed to be strongly associated to the biogeographic …

Technology Enabled Assessments: An Investigation of Scoring Models for Scaffolded Tasks
… for all of the scaffold items but ignored local dependence was determined to be the optimal scoring model for the assessment system used in this study. However, if the violation against the local independence assumption is deemed unacceptable, it was also concluded that the polytomous model …

High-dimensional and dependent data with additional structure
… approach is proposed to estimate the range of dependence along with the parameters of multivariate time series in high-dimensional settings. Theoretical results show that the two-step estimation approach reduces statistical error in high-dimensional settings. Simulation results confirm that the …
