Profile Matching in Observational Studies With Multilevel Data
(North Dakota State University, 2022)
Matching is a popular method to use with observational data to replicate desired features of a randomized control trial. A common problem encountered in observational studies is the lack of common support or the limited ...
Performance of Permutation Tests Using Simulated Genetic Data
(North Dakota State University, 2022)
Disease statuses and biological conditions are known to be greatly impacted by differences in gene expression levels. A common challenge in RNA-seq data analysis is to identify genes whose mean expression levels change ...
A Study of Locally D-optimal Designs for the Emax Model with Heteroscedasticity
(North Dakota State University, 2022)
The classic theory of locally optimal designs is developed on the center+error model assuming Gaussianity and homoscedasticity for random error, in which, the Maximum Likelihood Estimator (MLE) turns out to be the most ...
An Analysis of the NBA Draft: Are Teams Drafting Better and Does College Experience Truly Matter
(North Dakota State University, 2022)
This thesis attempts to answer two questions. Are NBA organizations doing a reasonable job at drafting players and getting better at the process, and does college experience play a significant role in a player’s performance ...
Estimating the Number of Genes That Are Differentially Expressed in Two Dependent Experiments or Analyses
(North Dakota State University, 2022)
Many researchers have used the intersection method to compare the results of differential expression analysis between two or more gene expression experiments. Some methods have been proposed to estimate the number of genes ...
A Comparison of the Ansari-Bradley Test and the Moses Test for the Variances
(North Dakota State University, 2011)
This paper is aimed to compare the powers and significance levels of two well known
nonparametric tests: the Ansari-Bradley test and the Moses test in both situations where
the equal-median assumption is satisfied and ...
Factors Influencing Carbon Sequestration in Northern Great Plains Grasslands
(North Dakota State University, 2011)
Soil development is influenced by the five soil forming factors; parent material,
climate, landscape, organisms and time. This study was designed to examine the effects of
landscape and organisms (vegetation) on carbon ...
A Pilot Study of Module Interconnectedness
(North Dakota State University, 2010)
Complexity plays an important role in understanding and working with a
program, and has been measured in many different ways for software applications. The
use of statistical analysis is one of the ways to predict the ...
Robust Tests for Cointegration with Application to Statistical Arbitrage Trading Strategies
(North Dakota State University, 2010)
This study proposes two new cointegration tests that employ rank-based and least absolute
deviation techniques to create a robust version of the Engle-Granger cointegration test.
Critical values are generated through a ...
The Influence of Race, Age, Comorbidities, and BMI on Disability Following Stroke in Elderly People Living in Their Own Home
(North Dakota State University, 2020)
Stroke is one of the major health issues in the United States. I explored different aspects of disability based on a history of stroke, race, comorbidities, age, and body mass index for the population of community dwelling ...
