Advanced Statistical Learning Approaches to Healthcare

Simsek, Serhat (2019-06-03)

In this dissertation, we propose a novel statistical modeling methodology that effectively analyzes and extracts information from large datasets. Two real datasets were employed to validate the proposed methodology: breast ...

An Analysis of Item Response Theory

Jones, Stuart (2019-07-02)

This paper examines a field of psychological and educational measurement testing theory called Item Response Theory. The paper delves into the basics of the theory, its theoretical and statistical background, and discusses ...

Deep Learning, Neural Networks and Aerospace Applications

Liting, Zhou (2018-11-15)

The ability to rack an enemy missile while in-flight, whether to accurately predict the point of impact (POI), the point of origin (POO) or to destroy the missile in-flight, is greatly enhanced if the missile type and/or ...

Developing Condition-Specific Hospice Formularies for Congestive Heart Failure and Depression Conditions and The Evaluation of Their Economic Impact

Khandelwal, Nikhil (2006-08-15)

With the increasing costs of providing pharmaceutical care, hospices in the U.S are burdened with the high costs of providing optimum healthcare. There is a need to implement cost-containment strategies such as drug ...

Environmental Effects On The Growth Of Young Longleaf Pine

Gilbert, John (2007-05-15)

A study to determine the effects of environmental conditions on the growth of young longleaf pine (Pinus palustris Mill) was initiated in 1969 on the Escambia Experimental Forest near Brewton, Alabama. Forty young longleaf ...

Estimating Cell-Type Profiles and Cell-Type Proportions in Heterogeneous Gene Expression Data

Pritchard, David A. (2012-05-16)

Understanding the mechanisms underlying natural variation in gene expression is an important question in medical and evolutionary genetics. Many studies intend to compare either (i) cell-type expression profiles across ...

Genuine Sequential Estimation Procedures for Gamma Populations using Exact Evaluation Criteria

Tolliver, Kevin (2009-12-09)

In this dissertation, we develop genuine two-stage sequential procedures for bounded-risk and fixed-width confidence interval estimation for Gamma distributed populations, based on exact evaluation criteria. The term ...

High-Dimensional Classification Methods for Sparse Signals and Their Applications in Text and Data Mining

Tadesse, Dawit (2014-07-22)

Classification using high-dimensional features arises frequently in many contemporary statistical studies such as tumor classification using microarray or other high-throughput data. In this dissertation we conduct a ...

Identifying Heterogeneous Disorders Through Normative Modeling of the Resting State BOLD Signal

Oldag, Ariel (2020-05-21)

One of the recent developments of interest in neuroscience is the detailed study intoresting state data. This data allows us to examine the way our brains behave in an awakestate with no tasks presented. ...

Lead-free Doped Solder Joint Reliability under Harsh Temperature Cycling Environment to study the Long Term Isothermal Aging Effects of Heat Sinks, Solder Paste Volume, Board Substrate Material, Component Substrate Material and Component Sizes

Thirugnanasambandam, Sivasubramanian (2018-07-23)

Restriction of Hazardous Substances (RoHS), Waste Electrical and Electronic Equipment Directive (WEEE) organizations have restricted the use of lead in solder materials for consumer electronics. The electronic industry ...

Location-Scale Bivariate Weibull Distributions For Bivariate

Han, Yi (2005-12-15)

Much research has been conducted over the last thirty years in the development and characterization of bivariate survival distributions. Typically, the multivariate distribution is derived assuming that the marginal ...

New Classes of Multivariate Gamma Survival and Reliability Models

Diawara, Norou (2006-08-15)

Multivariate modeling and analysis based on the multivariate normal distribution is well established and widely used. However, when the marginal distributions have only a positive support, such as time-to-event models, ...

On the Classification of Intermediate Range Missiles During Launch

Eckert, Jordan (2020-05-13)

This thesis explores the comparisons and contrasts of different statistical method approaches to a missile system classification which is sufficiently rapid to be suitable for use during engagement. It is meant to extend ...

Predictive Text Analytics and Text Classification Algorithms

Yucel, Ahmet (2016-05-23)
