  • Assessing Disparity Using Measures of Racial and Educational Isolation

    Open AccessMercedes A Bravo, Man Chong Leong et al.ARTICLEInternational Journal of…2021

    We develop a local, spatial measure of educational isolation (EI) and characterize the relationship between EI and our previously developed measure of racial isolation (RI). EI measures the extent to which non-college educated individuals are exposed primarily to other non-college educated individuals. To characterize how the RI-EI relationship varies across space, we propose a novel measure of local correlation. Using birth records from the Stat…

  • Maternal age, birth order, and race: Differential effects on birthweight

    Geeta K Swamy, Sharon Edwards et al.ARTICLEJournal of Epidemiology and…2012Cited by: 2References: 28

    BACKGROUND: Studies examining the influence of maternal age and birth order on birthweight have not effectively disentangled the relative contributions of each factor to birthweight, especially as they may differ by race. METHODS: A population-based, cross-sectional study of North Carolina births from 1999 to 2003 was performed. Analysis was restricted to 510 288 singleton births from 28 to 42 weeks' gestation with no congenital anomalies. Multiv…

  • Gradients in Spatial Response Surfaces With Application to Urban Land Values

    Anandamayee Majumdar, Henry J Munneke et al.ARTICLEJournal of Business and Economic…2006

    For point-referenced spatial data, we often create explanatory models that introduce regression structure with error consisting of a spatial term and a white noise term. Here we consider more flexible regression structures that allow spatially varying regression coefficients. The resulting mean becomes a spatial response surface that is a linear combination of the components of the spatially varying coefficient vector. Of possible interest in thi…

  • Spatial Modeling of House Prices Using Normalized Distance-Weighted Sums of Stationary Processes

    Sudipto Banerjee, Alan E Gelfand et al.ARTICLEJournal of Business and Economic…2004

    Hedonic models are used almost universally for modeling house prices. Recognizing the importance of location, the past decade has seen increasing effort to introduce spatial considerations into such modeling. When spatial process models are used to capture association between locations, isotropic specifications have been used almost exclusively despite the fact that they seem unlikely to be appropriate in practice. The contribution of this articl…

  • Spatio-Temporal Modeling of Residential Sales Data

    Alan E Gelfand, Sujit K Ghosh et al.ARTICLEJournal of Business and Economic…1998

    This article focuses on the location, time, and spatio-temporal components associated with suitably aggregated data to improve prediction of individual asset values. Such effects are introduced in the context of hierarchical models, which we find more natural than attempting to model covariance structure. Indeed, our cross-sectional database, a sample of 7,936 transactions for 49 subdivisions over a 10-year period in Baton Rouge, Louisiana, precl…

  • Sampling-Based Approaches to Calculating Marginal Densities

    Alan E Gelfand, Adrian F M SmithARTICLEJournal of the American…1990

    Stochastic substitution, the Gibbs sampler, and the sampling-importance-resampling algorithm can be viewed as three alternative sampling- (or Monte Carlo-) based approaches to the calculation of numerical estimates of marginal probability distributions. The three approaches will be reviewed, compared, and contrasted in relation to various joint probability structures frequently encountered in applications. In particular, the relevance of the appr…

  • Seriation Methods for Archaeological Materials

    Open AccessAlan E GelfandARTICLEAmerican Antiquity1971Cited by: 4References: 5

    This paper considers two recently developed mathematical techniques in archaeological seriation. Both techniques take as given, a similarity matrix between the objects to be ordered. The first method is a 'linkage' procedure, while the second (and preferred) is an 'averaging' procedure. The second method, though a bit more mathematical, has been very successful in application to real data. Both techniques have several good features which will be …
