Statistical methodology motivated by problems in genetics
… important challenge in statistics is to develop methodology to extract information from this data. In this thesis, developments are made in two methodological areas that have wide applications in genetics. First, probabilistic methods to deal with the label switching problem in Bayesian mixture …

Luce's Challenge: Quantitative Models and Statistical Methodology
… probabilistic ones as well as develop general statistical methodologies to test these new, suitably transformed, decision theories. Under this framework, I examine the axiom of transitivity and the non-compensatory lexicographic semiorder model in detail."

The mathematical-statistical methodology of the contemporary Soviet family budget survey
The study describes and assesses the mathematical-statistical methodology of the contemporary Soviet Family Budget Survey, both in regard to the sample design and in regard to the processing and analysis of the survey data. A wide range of methodological deficiencies are identified, accounting for …

A concentration inequality based statistical methodology for inference on covariance matrices and operators
… of high and infinite dimensional data, classical statistical methodology is often rendered inefficient and ineffective when confronted with such big data problems as arise in genomics, medical imaging, speech analysis, and many other areas of research. Many problems manifest when the practitioner …

Application of statistics to the study of cognitive processes in mathematics education : a case study of theoretical thinking as a factor of students' success in linear algebra
… the possibility of applying different forms of statistical analysis to these data is conducted from different perspectives on statistical methodology namely, descriptive/exploratory statistics and statistical modeling. A number of indices for measuring theoretical behavior tendencies are defined …

Hazard rate models for early warranty issue detection using upstream supply chain information
<p>This research presents a statistical methodology to construct an early automotive warranty issue detection model based on upstream supply chain information. This is contrary to extant methods that are mostly reactive and only rely on data available from the OEMs (original equipment …

On the detection of seasonal variation in the onset of disease
… of their aetiology. This thesis studies statistical methodology for seasonality which can be summarised by a single peak or multiple peaks determined by patient characteristics or external influences. The circular, rather than linear, nature of the date of onset means that Normal …

The Statistical Exploration in the $G$-expectation Framework: The Pseudo Simulation and Estimation of Variance Uncertainty
… necessary to build up the associated statistical methodology. This thesis explores the emph{computation, simulation, and estimation} of the $G$-normal distribution (a typical distribution with variance uncertainty) by constructing a new substructure called the emph{Semi-$G$-normal …

New Deal, New Details: Statistical Governance and the 1940 Census
Statistical information fuels modern states. How did statistics become so integral to modern forms of governance? This study examines the development of the United States' 1940 Decennial Census questionnaire, which introduced questions about housing, income, and unemployment. It was also the first …
