Nonparametric prediction in survey sampling and its application to the nonresponse problem
… regression model is ubiquitous in the sample survey literature, an assumption that is untenable in practice. In this dissertation we illustrate that it is feasible to estimate a finite population mean (also in the presence of nonresponse) with a nonparametric regression model. The simulations …

Customer Perceptions of Fairness in Hotel Revenue Management.
… of fairness. Convenience-Interception survey sampling was used to collect 460 sample data at the Dallas Love Field Airport. After analyzing data, one can infer that when revenue management information was provided, customers are satisfied. Further, age, education, Airline FFP enrolled …

Online Voting Platforms and the Future of Voter Turnout
… confirmation of perceived benefits and problems. Surveying 196 U.S. citizens through Survey Sampling International, this study garnered respondents' feelings toward several factors correlated with voter-turnout, and the likelihood of adopting OVPs. Using the Unified Theory of Acceptance and …

HIV surveillance : a 12 year analysis of HIV prevalence trends and comparing HIV prevalence from sentinel antenatal clinic surveys and prevention of mother-to-child programmes
Background Sentinel antenatal clinic (ANC) surveys remain a key source of data on HIV prevalence trends. Recently though, with an increase in the uptake of prevention of mother-to-child transmission (PMTCT) programmes, there have been debates on the prospects of using PMTCT data for reporting …

THE INFLUENCE OF RANGE SHIFTS AND WIND ENERGY ON THE ATLANTIC SURFCLAM (SPISULA SOLIDISSIMA) AND OCEAN QUAHOG (ARCTICA ISLANDICA) FISHERIES ON THE U.S. OUTER CONTINENTAL SHELF
… after wind farm implementation. A 2021 at-sea survey sampling of the overlap region was also conducted with the purpose of mapping fishable concentrations of surfclams and ocean quahogs. Species overlap between surfclams and ocean quahogs is most prominent in the 40-55-m depth range where size …

Statistical learning with differential privacy
… intervals for population proportions in survey sampling, (2) addressing private linear regression with uncertainties from prior data linkage, and (3) investigating private stochastic gradient descent algorithms. Differentially private algorithms for the first two tasks are designed using …

Spatial management of groundfish resources in the Gulf of Maine and Georges Bank
… patterns constructed from NMFS bottom-trawl surveys (1971--2005) demonstrated that fish species richness increased in some areas, as species evenness declined. Fish species composition changed from demersal species to more abundant pelagic species inside and outside of the fisheries closures. …

Essays on trade barriers in imperfectly competitive markets
… competition is assumed. The first essay is a survey sampling recent papers dealing with the topics mentioned above. Specifically, we choose papers on trade barriers in imperfectly competitive markets, according to the types of models--static vs dynamic--and to the types of trade …

Weighting and moment conditions in Bayesian inference
… can choose to implement an unequal probability sampling frame to optimize efficiency subject to constraints. If so, the probability weights are known and are traditionally equal to the inverse of the unit sampling probabilities. It is often the case, however, that the sampling mechanism is …

Beyond Parameter Estimation: Analysis of the Case-Cohort Design in Cox Models
… studies generally consider full cohort sizes, sampling fractions, and case percentages that are dissimilar to those seen in practice. In this thesis the design of the simulation studies aims to provide circumstances which are similar to those encountered when using case-cohort designs in …

Food innsecurity and quality of life in informal settlements of Katutura, Windhoek, Namibia
… quantitative design through a two-stage cluster survey sampling was applied. The sample size of the study was 416 respondents selected from 40 Primary Sampling Units (PSU’s). The research instrument used in this study was the face to face administered questionnaire, distributed to 416 …

Statistical modelling and inference for financial auditing
… In such populations the use of the classical survey-sampling estimators such as the mean-per-unit, the difference, the ratio or regression, based on the normality assumption of the sampling distribution of the estimates, has been found unreliable, (e.g. Stringer 1963, Kaplan 1973, and Neter …

Structured evaluation of attitudes to dwelling environments : people’s subjective assessments of preference satisfaction and meaning as indicators of architectural design performance
… research product - comprises an evaluation of survey techniques and the concepts they measure (such as 'satisfaction'), and a review of the philosophical and methodological consequences of adopting the holistic viewpoints of Phenomenology and Communication Theory in either conceptualising, …

Population Estimation Procedures For Elk and Deer in the Black Hills, South Dakota: Development of a Sightability Model and Spotlight Survey
… of total counts when conducting aerial surveys for ungulates. The Black Hills of South Dakota are characterized by dense ponderosa pine (Pinus ponderosa), which affects sightability and accurate censusing of elk (Cervus elaphus). Few studies have evaluated aerial survey methodology for …
