Ds-Optimal Design for Model Discrimination in a Probit Model
(North Dakota State University, 2014)In toxicology studies, dose response functions with a downturn at higher doses are often observed. For such response functions, researchers often want to see if the downturn of the response is signifcant. A probit model ... -
Exploring Associations between Lifestyles and Metabolic Syndrome in Middle-Age Chinese Population
(North Dakota State University, 2018)Nowadays the prevalence of Metabolic Syndrome (MetS) affects many middle-age people in China. MetS is associated with the risk of type 2 diabetes and cardiovascular disease. Identifying the potential risk factors contribute ... -
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 ... -
Forecasting Point Spread for Women’s Volleyball
(North Dakota State University, 2016)Volleyball has become a well-known and competitive sport with physical and technical performances over the years. The game results are determined by some important factors such as players, and the team’s skills to succeed ... -
Identifying Significant Factors Influencing Metabolic Syndrome In China
(North Dakota State University, 2015)Metabolic Syndrome occurs when a person’s body does not properly use and store energy. The disease has five criteria: abdominal obesity, insulin resistance, hypertension, dyslipidemia, and impaired glucose regulation. The ... -
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 ... -
Investment Behavior Analysis Based on Tail Risk Management
(North Dakota State University, 2018)As behavioral finance is becoming more prevalent in academic area, a study is worth conducting to pinpoint investors’ preference through managing tail risk of asset portfolios. This study investigates investors’ investment ... -
Optimal Designs for the Hill Model with Three Parameters
(North Dakota State University, 2012)Optimal designs specify design points to use and how to distribute subjects over these design points in the most efficient manner. The Hill model with three parameters is often used to describe sigmoid dose response ... -
Optimizing Prediction Power of RNA-seq on Intrinsic Characteristics in Breast Cancer
(North Dakota State University, 2022)Breast cancer is the most common cancer in women worldwide, and accurate and early detection of breast cancer is vital in characterizing the disease. Transcriptomic expression is embedded abundant tumor and cell state ... -
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 ... -
Prediction of the World Cup Soccer Winner: Using Two Statistical Methods
(North Dakota State University, 2016)Soccer is considered the most popular sport on earth and applying statistical models to analyze small soccer data has been of a keen interest to modern researchers. Statistical modeling of soccer data also provides guidance ... -
A Proposed Nonparametric Test for Simple Tree Alternative in a BIBD Design
(North Dakota State University, 2011)A nonparametric test is proposed to test for the simple tree alternative in a Balanced Incomplete Block Design (BIBD). The details of the test statistic when the null hypothesis is true are given. The paper also introduces ... -
Robust D-Optimal Design for Multiple Nominal Parameter Values under the 5PL-1P Model
(North Dakota State University, 2018)A robust D-optimal design that works well for multiple nominal parameter values is presented in this paper. In general, D-optimal design works very well for estimating the model parameters, but it is very sensitive to ... -
Robust D-Optimal Design for Response Functions with a Downturn
(North Dakota State University, 2013)Researchers studying dose-response relationships must allocate limited resources to design points in order to maximize the information gained from the study. D-optimal design is a well-described design that works efficiently ... -
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 ... -
Rutin Extraction and Content in Buckwheat (Fagopyrum esculentum) Bran-Fortified Pasta
(North Dakota State University, 2019)The objectives of this study were to optimize extraction of rutin from buckwheat bran and buckwheat bran-fortified spaghetti and to determine the stability of rutin during spaghetti production and preparation. Aqueous ...
