  • Semiparametric marginal and mixed models for longitudinal data

    Creator:
    Tsai, Guei-Feng
    Abstract:
    This thesis consists of three papers which investigate marginal models, nonparametric approaches, generalized mixed effects models and variance components estimation in longitudinal data analysis. In the first paper, a new marginal approach is introduced for high-dimensional cell-cycle microarray data with no replicates. There are two kinds of correlation for cell-cycle...

  • Estimating population totals from area frame samples

    Creator:
    Garoui, Abderrazak
    Abstract:
    Area frame sampling for agricultural statistics is a procedure currently used by the Statistical Reporting Service of the US Department of Agriculture as well as by agriculture departments in other countries. A primary advantage of the area frame is that it provides complete coverage of the population. In area frame...

  • Tools for environmental statistics : creative visualization and estimating variance from complex surveys

    Creator:
    Courbois, Jean-Yves Pip
    Abstract:
    Environmental monitoring poses two challenges to statistical analysis: complex data and complex survey designs. Monitoring for system health involves measuring physical, chemical, and biological properties that have complex relations. Exploring these relations is an integral part of understanding how systems are changing under stress. How does one explore high dimensional...

  • Statistical surface wind forecasting at Goodnoe Hills, Washington

    Creator:
    Curtis, Joel C.
    Abstract:
    Multiple linear regression was used to develop equations for 12-, 24-, and 36-hour surface wind forecasts for the wind energy site at Goodnoe Hills. Equations were derived separately for warm and cool seasons. The potential predictors included LFM II model output, MOS surface wind forecasts extrapolated from surrounding stations, pressure...

  • Efficient classification for longitudinal data

    Creator:
    Wang, Xianlong
    Abstract:
    We propose a new classification method for longitudinal data based on a semiparametric approach. Our approach builds a classifier by taking advantage of modeling information between response and covariates for each class, and assigns a new subject to the class with the smallest quadratic distance. This enables one to overcome...

  • Higher-level Analysis of RNA-Seq Experiment: Multiple Data Sets and Multiple Genes

    Creator:
    Zhuo, Bin
    Abstract:
    Differential expression (DE) analysis is a key task in gene expression study, because it uncovers the association between expression levels of a gene and the covariates of interest. This dissertation pertains to two particular aspects of DE analysis—identifying stably expressed genes for count normalization and accounting for correlation between DE...

    Creator:
    Xu, Tanjin
    Abstract:
    An important impact of the genome technology revolution will be the elucidation of mechanisms of cancer pathogenesis, leading to improvements in the diagnosis of cancer and the selection of cancer treatment. Integrated with current well-studied massive knowledge and findings about the role of protein-coding mutations in cancer, demystifying the functional...

  • Estimation of totals for skewed populations in repeated agricultural surveys

    Creator:
    Viroonsri, Boonchai
    Abstract:
    The National Agricultural Statistical Service (NASS) conducts quarterly surveys for estimation of some primary commodities produced on farms and ranches. The commodities often have highly skewed distributions with a few farms producing very large amounts. NASS uses dual sampling frames comprised of the list frame for efficient stratification and the...

  • Conditioning of unobserved period-specific abundances to improve estimation of dynamic populations

    Creator:
    Dail, David
    Abstract:
    Obtaining accurate estimates of animal abundance is made difficult by the fact that most animal species are detected imperfectly. Early attempts at building likelihood models that account for unknown detection probability impose a simplifying assumption unrealistic for many populations, however: no births, deaths, migration or emigration can occur in the...
