Topics in 2-categorical Algebra
… thesis we will examine 2-categories and higher categorical structures and formulate 1-categorical theorems in the language of higher categories as well as formulate some internal definitions of these base structures in finitely complete categories. We will begin by defining the relevant 2- …

Sequential analysis of categorical data
… have been developed for sequential analysis of categorical data group-wise. These procedures' enables (i) a simple hypothesis to be used for the alternative hypothesis instead of the composite hypothesis commonly used in goodness-of-fit tests, contingency tables, and Mood's non-parametric …

Bayesian analysis for categorical survey data
… methodology for univariate and multivariate categorical survey data. The Multinomial model is used and the following problems are addressed. Limited information about the design variables leads us to model the unknown design variables taking into account the sampling scheme. Random effects …

Empirical analyses of dynamic categorical data
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Essay 1 analyzes the married couples' retirement decision using the PSID data. I employ the proportional hazard model to examine the factors that influence the retirement decision of husband and wife, and focus on …

Treemaps: Visualizing Hierarchical and Categorical Data
… method for the visualization of hierarchical and categorical data sets. Treemap presentations of data shift mental workload from the cognitive to the perceptual systems, taking advantage of the human visual processing system to increase the bandwidth of the human-computer interface. Efficient use …

Bayesian model determination for categorical data survey
… to misleading results. The standard analysis of categorical data, developed under the assumption of multinomial sampling, is inadequate as the commonly used sampling schemes clearly violate this assumption. Since, Kish (1965) introduced the idea of a design effect, many classical solutions have …

Categorical semantics and composition of tree transducers
In this thesis we see two new approaches to compose tree transducers and more general to fuse functional programs. The first abroach is based on initial algebras. We prove a new variant of the acid rain theorem for mutually recursive functions where the build function is substituted by a concrete …

Categorical models of second-order abstract syntax
… verification has been limited, due to their categorical sophistication and the challenges of encoding them in dependently-typed settings. This thesis bridges this gap by formally relating the method of intrinsically typed encodings to the presheaf approach for languages with binding. We …

Dualities and Categorical Structures from 2D Up
… upon the key tools of holographic duality and categorical algebraic geometry. The use of the former is justified by the lack of a non-perturbative formulation of String Theory, whereas the latter is dictated by the great advancement there has been in the past decades in studying algebraic …

A Wyler-type approach to categorical topology
… completeness, then the concepts of a categorical completion and an order-theoretic completion are more closely related, as shown by the result that for certain kinds of cofibrations, taking the universal order-theoretic completion of each fibre even yields the universal final …

Topics in categorical algebra and Galois theory
We provide an overview of the construction of categorical semidirect products and discuss their form in particular semi-abelian varieties. We then give a thorough description of categorical Galois theory, which yields an analogue for the fundamental theorem of Galois theory in an abstract category …

A language-based approach to categorical analysis
With the digitization of media, computers can be employed to help us with the process of classification, both by learning from our behavior to perform the task for us and by exposing new ways for us to think about our information. Given that most of our media comes in the form of electronic text, …

Evaluation of Imputation Methods Focusing on Categorical Outcomes
… with synthetic data focusing on imputation for categorical variables. The results enable us to suggest guidelines regarding impact of imputation consider ing dataset aspects such as percentage of incomplete data missing, missing mechanisms (MAR – missing at random, MCAR – missing completely at …

Arithmetical, geometrical, and categorical forays into particle physics
This Thesis will focus on three different forays into particle physics using pure mathematics. Our first foray studies anomaly free gauge algebras. Using geometric methods, we reproduce a solution given to the anomaly cancellation conditions associated with a pure u(1)-gauge theory in Costa et al. …

Investigations into the categorical foundations of homotopy theory
… thesis is twofold - to give an account of the categorical foundations of homotopy theory, and to illuminate some aspects of category theory by showing the role played by the formation or quotient categories in many parts of general theory. Chapter 1 defines and classifies various types of …

What lies beneath? : a defense of categorical humility
… develop and defend a new Humility thesis, Categorical Humility. Humility theses tell us there is some fundamental aspect of the world that we lack knowledge of. All such theses share two parts: an existence claim, stating that there is in fact this portion of the world, and an ignorance …

The categorical funding of consumer and homemaking education
… Education Act to include, among other things, categorical funding for consumer and homemaking education. The purpose of this study was to discover why consumer and homemaking education received categorical funding in that legislation. This research was a policy formulation study. In order to …

A 2-categorical extension of the Reshetikhin--Turaev theory
<p>We concretely construct a 2-categorically extended topological quantum field theory that extends the Reshetikhin-Turaev TQFT to cobordisms with corners. The source category will be a well chosen 2-category of decorated cobordisms with corners and the target bicategory will be the …
