  • Variable selection in semi-parametric models

    Creator:
    Jiang, Shuping
    Abstract:
    We consider two semiparametric regression models for data analysis, the stochastic additive model (SAM) for nonlinear time series data and the additive coefficient model (ACM) for randomly sampled data with nonparametric structure. We employ the SCAD-penalized polynomial spline estimation method for estimation and simultaneous variable selection in both models. It...

  • Analysis of epidemiological data with covariate errors

    Creator:
    Delongchamp, Robert
    Abstract:
    In regression analysis, random errors in an explanatory variable cause the usual estimates of its regression coefficient to be biased. Although this problem has been studied for many years, routine methods have not emerged. This thesis investigates some aspects of this problem in the setting of analysis of epidemiological data....

  • Explicit linear maximum likelihood estimation in mixed models

    Creator:
    Wulff, Shaun S.
    Abstract:
    Mixed models have been widely used to model data from experiments which have fixed and random factors. Often there is interest in the estimation of fixed effects and variance components. The likelihood procedure is a general technique that has been applied to such problems. This procedure can be computationally difficult,...
