    • Coevolution Regression and Composite Likelihood Estimation for Social Networks 

      He, Yanjun
      We study how social networks and nodal attributes influence each other over time. A multiplicative coevolution regression (MCR) model is proposed for longitudinal network and nodal attribute data. The coevolution model is ...
    • Model-Based Penalized Regression 

      Griffin, Maryclare Carney
      This thesis contains three chapters that consider penalized regression from a model-based perspective, interpreting penalties as assumed prior distributions for unknown regression coefficients. In the first chapter, we ...
    • Modeling Heterogeneity within and between Matrices and Arrays 

      Fosdick, Bailey Kathryn (2013-11-14)
      Datasets in the form of matrices and arrays arise frequently in the social and biological sciences and are characterized by measurements indexed by two or more factors. In this dissertation we address two problems relating ...
    • Statistical inference using Kronecker structured covariance 

      Volfovsky, Alexander (2013-11-14)
      We present results for testing and estimation in the context of separable covariance models. We concentrate on two types of data: relational data and cross-classified data. Relational data is frequently represented by a ...
