  • A cooperative work experience approach to in-service staff development for selected community colleges

    Creator:
    Visger, Dale Bennett
    Abstract:
    The major purpose of this research was to study the in-service programs for community college vocational instructors, and develop guidelines for a cooperative work experience approach to in-service staff development. The specific objectives of the study were: (1) To develop a research instrument capable of measuring the agreement relative to...

  • Statistical estimation for initiative petitions and performance of the decision rule for Oregon state petitions

    Creator:
    Smith-Cayama, Rubén A.
    Abstract:
    Two topics concerning statistical sampling of initiative petitions are considered in this dissertation. The first concerns statistical estimation of the number of distinct valid signatures in a petition, and the second evaluates the statistical decision rule used by Oregon for determining certification of state initiative and referendum petitions. In several...

  • Laplace approximations to likelihood functions for generalized linear mixed models

    Creator:
    Liu, Qing, 1961-
    Abstract:
    This thesis considers likelihood inferences for generalized linear models with additional random effects. The likelihood function involved ordinarily cannot be evaluated in closed form and numerical integration is needed. The theme of the thesis is a closed-form approximation based on Laplace's method. We first consider a special yet important case...

  • The use of logistic regression for developing habitat association models

    Creator:
    Sjamsoe'oed, Roza
    Abstract:
    Quantitative habitat models of wildlife-habitat relationships are developed to formalize our current understanding about an ecological system. A habitat association model is one of these models that is useful for answering questions about how the habitat is occupied, how much growth habitat is required by the animal, or how the...

  • Estimation of discriminant analysis error rate for high dimensional data

    Creator:
    Lebow, Patricia K.
    Abstract:
    Methodologies for data reduction, modeling, and classification of grouped response curves are explored. In particular, the thesis focuses on the analysis of a collection of highly correlated, highly dimensional response-curve data of spectral reflectance curves of wood surface features. In the analysis, questions about the application of cross-validation estimation of...

  • A linear programming and sampling approach to the cutting-order problem

    Creator:
    Hamilton, Evan D.
    Abstract:
    In the context of forest products, a cutting order is a list of dimension parts along with demanded quantities. The cutting-order problem is to minimize the total cost of filling the cutting order from a given lumber grade (or grades). Lumber of a given grade is supplied to the production...

  • Forest industry restructuring and emerging forest tenures in Deschutes and Klamath Counties, Oregon

    Creator:
    Kelly, Erin Clover
    Abstract:
    Since the 1980s, industrial forest restructuring has resulted in the divestment of industrial timberlands across the U.S. Emerging tenures have benefited from the divestment, including conservation-based tenures that manage for multiple objectives such as restoration, recreation access, and forest and habitat contiguity. Deschutes and Klamath Counties, Oregon, have three proposed...

  • Estimating absence

    Creator:
    Kincaid, Thomas M.
    Abstract:
    The problem addressed is absence of a class of objects in a finite set of objects, which is investigated by considering absence of a species and absence in relation to a threshold. Regarding absence of a species, we demonstrate that the assessed probability of absence of the class of objects...

  • Localized Variable Selection with Random Forest

    Creator:
    Niyaghi, Faraz
    Abstract:
    Due to recent advances in computer technology, the cost of collecting and storing data has dropped drastically. This makes it feasible to collect large amounts of information for each data point. This increasing trend in feature dimensionality justifies the need for research on variable selection. Random forest (RF) has demonstrated...

  • Spatial graphical models with discrete and continuous components

    Creator:
    Che, Xuan
    Abstract:
    Graphical models use Markov properties to establish associations among dependent variables. To estimate spatial correlation and other parameters in graphical models, the conditional independences and joint probability distribution of the graph need to be specified. We can rely on Gaussian multivariate models to derive the joint distribution when all the...
