Empirical Bayes and item-clustering effects in a latent variable hierarchical model: a case study from the National Assessment of Educational Progress.(Statistical Data Included)

From: Journal of the American Statistical Association | Date: June 1, 2002| Author: Ip, Edward H.; Scott, Steven L. | Copyright information

Empirical Bayes regression procedures are often used in educational and psychological testing as extensions to latent variables models. The National Assessment of Educational Progress (NAEP) is an important national survey using such procedures. The NAEP applies empirical Bayes methods to models from item response theory to calibrate student responses to questions of varying difficulty. Due partially to the limited computing technology that existed when NAEP was first conceived, NAEP analys...

Biophysical Journal ; ABSTRACT Intercellular adhesion mediated by integrin ?^sub 4sub 1^ and vascular cell adhesion molecule-1 (VCAM-1) plays a crucial role in both the rolling and firm attachment of leukocytes onto the vascular endothelium. Essential to the ?^sub 4sub 1^/VCAM-1 interaction is its mechanical strength
Development of Mo(Si,Al)^sub 2^-Base Oxidation-Resistant Coating on Nb-Base Structural Materials
Metallurgical and Materials Transactions ; Mo(Si,Al)^sub 2^-base oxidation-resistant coatings for Nb-base structural materials have been studied. The coating is composed of a Mo(Si, Al)^sub 2^-base Al reservoir and Al^sub 2^O^sub 3^ interlayer to suppress interface reactions between the Al reservoir and the substrate. To develop a suitable

Metallurgical and Materials Transactions ; The viscosity of CaO-SiO^sub 2^ (-MgO)-Al^sub 2^O^sub 3^ slags was measured to clarify the effects of Al^sub 2^O^sub 3^ and MgO on the structure and viscous flow of molten slags at high temperatures. Furthermore, the infrared spectra of the quenched slags were analyzed to understand the structural
On the number of maximal subgroups and theta pairs in a finite group.
International Journal of Applied Mathematics & Statistics ; ABSTRACT Let M be a maximal subgroup of a finite group G. The pair (A, B) of subgroups of G is called a [theta]-pair of M if the following conditions hold: (a) B G, B < A, (b) < M, A >= G and B [less than or equal to] M and (c) A/B has no proper normal subgroup of G/B. In this paper, we
