  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 ...

• A Study of Locally D-optimal Designs for the Emax Model with Heteroscedasticity 

  Zhang, Xiao (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 

  Wolfe, Kevin (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 ...

• Performance of Permutation Tests Using Simulated Genetic Data 

  Soumare, Ibrahim (North Dakota State University, 2022)

• Comparing Prediction Accuracies of Cancer Survival Using Machine Learning Techniques and Statistical Methods in Combination with Data Reduction Methods 

  Mostofa, Mohammad (North Dakota State University, 2022)

  This comparative study of five-year survival prediction for breast, lung, colon, and leukemia cancers using a large SEER dataset along with 10-fold cross-validation provided us with an insight into the relative prediction ...

• Proposed Nonparametric Tests for the Umbrella Alternative in a Mixed Design Testing for Location and Location-Scale 

  Alotaibi, Eid Sadun (North Dakota State University, 2022)

  Researchers sometimes use the umbrella alternative when testing for differences in treatment effects, where the parameters increase up to a point and decrease after that point. Sometimes different treatment effects may ...

• Optimizing Prediction Power of RNA-seq on Intrinsic Characteristics in Breast Cancer 

  Liu, Yuan (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 ...

• Comparing Prediction Methods of Wheat Grain Quality With the Area Under the Receiver Operating Characteristic Curves 

  Lin, Ying (North Dakota State University, 2021)

  A widely used breeding method is genomic selection, which uses genome-wide marker coverage to predict genotypic values for quantitative traits. Genomic selection combines molecular and phenotypic data in a training population ...

• A Comparative Multiple Simulation Study for Parametric and Nonparametric Methods in the Identification of Differentially Expressed Genes 

  Palmer, Daniel Grant (North Dakota State University, 2021)

  RNA-seq data simulated from a negative binomial distribution, sampled without replacement, or modified from read counts were analyzed to compare differential gene expression analysis methods in terms of false discovery ...

• A Simulation Study Using a Mixed Model Framework to Analyze the Impact of Sample Size and Variability on Type I Error and Power 

  Gu, Xiaoxue (North Dakota State University, 2021)

  Repeated measures design (or longitudinal study) are commonly seen in many research fields, especially in pharmaceutical clinical trials, agricultural research, and psychology. PROC MIXED (SAS Inc.) is a well-known standard ...

• Robustness of the Eigenvalue Test for Community Structure 

  Rose, Matthew Allan (North Dakota State University, 2021)

  Networks can take on many different forms, such as the people from the University you attend. Within these networks, community structure may exist. This "community structure" refers to the clustering of nodes by a common ...

• On Lasso Estimation of Linear Mixed Model for High Dimensional Longitudinal Data 

  Wen, Qian (North Dakota State University, 2021)

  With the advancement of technology in data collection, repeated measurements with high dimensional covariates have become increasingly common. The classical statistics approach for modeling the data of this kind is via the ...

• A Spectral Two Sample Test 

  Xu, Yangshuang (North Dakota State University, 2021)

  In statistics, two-sample tests are commonly desired under many topics. It's crucial to differentiate populations as a prerequisite for developing further analysis. A number of statistical tests have been developed for ...
