  • Propensity score adjustments using covariates in observational studies

    Yang, Daniel K.
    Abstract:
    In this thesis we develop a theoretical framework for the identification of situations where the equal frequency (EF) or equal variance (EV) subclassification may produce lower bias and/or variance of the estimator. We conduct simulation studies to examine the EF and EV approaches under different types of model misspecification. We...

  • A Linear Mixed Model Framework for Spatio-Temporal Random Processes using the Separable and Product-Sum Covariance Structures

    Creator:
    Dumelle, Michael J.
    Abstract:
    We describe spatio-temporal random processes using linear mixed models and discuss estimation, inference, and prediction under this formulation. We show how many commonly used covariances are special cases of this more general framework and pay special attention to the separable and product-sum covariances. The linear mixed model formulation facilitates straightforward...

  • Predator Conservation and Trophic Ecology

    Wolf, Christopher
    Abstract:
    Many of Earth’s terrestrial large carnivore species are threatened with extinction. As a result, some of the ecological effects associated with these species may be lost. With the goal of furthering large carnivore conservation research, I conduct three global scale analyses involving these species. First, I explore prey depletion as...
