A goodness-of-fit test for regression models with spatially correlated errors
Andrea Meilán-Vila, Jean D. Opsomer, Mario Francisco-Fernández +1
The problem of assessing a parametric regression model in the presence of spatial correlation is addressed in this work. For that purpose, a goodness-of-fit test based on a -d…
A Correlated Random Effects Model for Nonignorable Missing Data in Value-Added Assessment of Teacher Effects
Andrew T. Karl, Yan Yang, Sharon L. Lohr
Value-added models have been widely used to assess the contributions of individual teachers and schools to students' academic growth based on longitudinal student achievement outco…
Computation of Maximum Likelihood Estimates for Multiresponse Generalized Linear Mixed Models with Non-nested, Correlated Random Effects
Andrew T. Karl, Yan Yang, Sharon L. Lohr
Estimation of generalized linear mixed models (GLMMs) with non-nested random effects structures requires approximation of high-dimensional integrals. Many existing methods are tail…
Efficient Maximum Likelihood Estimation of Multiple Membership Linear Mixed Models, with an Application to Educational Value-Added Assessments
Andrew T. Karl, Yan Yang, Sharon L. Lohr
The generalized persistence (GP) model, developed in the context of estimating ``value added'' by individual teachers to their students' current and future test scores, is one of t…
