  • Predator Conservation and Trophic Ecology

    Creator:
    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...

  • Statistical methods for serially correlated zero-inflated proportions

    Creator:
    Sun, Luna
    Abstract:
    Proportion data falling in the continuum (0, 1) are very common in practice. It can also happen that an inflated number of zeros (or ones) occur with proportion data. There are extensive studies of zero-inflated data in the literature. Almost all of them, however, focus on zero-inflated count data. Furthermore,...

  • The laplace approximation and inference in generalized linear models with two or more random effects

    Creator:
    Pratt, James L.
    Abstract:
    This thesis proposes an approximate maximum likelihood estimator and likelihood ratio test for parameters in a generalized linear model when two or more random effects are present. Substantial progress in parameter estimation for such models has been made with methods involving generalized least squares based on the approximate marginal mean...

  • Model-based Clustering Methods in Exploratory Analysis of RNA-Seq Experiments

    Creator:
    Zhang, Wanli
    Abstract:
    Differential expression (DE) analysis allows us to identify genes that respond differently under varying experimental conditions, therefore granting us an understanding of the molecular basis of phenotypic variation. Following the identification of significantly differentially expressed genes, it is often of the researcher's interest to elucidate hidden patterns or groups in...

  • Estimation and Sparse Selection of Conditional Probability Models for Vector Time Series

    Creator:
    Ruiz, Trevor D.
    Abstract:
    Diverse scientific fields collect multiple time series data to investigate the dynamical behavior of complex systems: atmospheric and climate science, geophysics, neuroscience, epidemiology, ecology, and environmental science. Identifying patterns of mutual dependence among such data generates valuable knowledge that can be applied either for inferential or forecasting purposes. Vector autoregressive...
