Statistical Methods for In-session Hemodialysis Monitoring
… and better accuracy regardless of types of samples. We proposed a two sample hypothesis testing on groups of baseline-corrected Raman spectra with ISREA. The uniqueness of the test lies in nature of the tested data. Instead of using Raman spectra as curves, we also consider a vector whose …

Rank-based Two Sample Tests Under a General Alternative
The problem of testing whether two samples come from the same or different population is a classical one in statistics. In this dissertation, I first study rank based formulation of univariate two-sample distribution-free tests. One form of the test statistic is the average of between-group …

Statistical inference for high-dimensional data
… [Gretton et al. (2008)] and related independence tests under the high dimensional scenario. We show that the sample distance/Hilbert-Schmidt covariance between two random vectors can be approximated by the sum of squared componentwise sample cross-covariances up to an asymptotically constant …

Revisiting Generalization for Deep Learning: PAC-Bayes, Flat Minima, and Generative Models
… of unsupervised learning. We propose to use a two sample test statistic for training neural network generator models and bound the gap between the population and the empirical estimate of the statistic.

Effects of Habitat on Population Density of Centrarchid Species in the James River, Missouri
… Seven sites on the James River, Missouri were sampled two times each using a backpack electroshocker. Centrarchids were identified and measured. Habitat was measured. Macroinvertebrates were collected. Catch per unit effort (CPUE) was calculated for each centrarchid species, and principal …

Hypothesis testing and causal inference with heterogeneous medical data
… genetic data with only few observed samples, biases and spurious correlations are prevalent. These are called spurious because they do not contribute to the effect being studied. In this context, the modelling assumptions of existing statistical tests and causal inference methods are …

Statistical Learning for Sequential Unstructured Data
… learning abilities. The emergence of neural network tools has enabled scalable learning for high-dimensional sequential data. From an algorithmic perspective, efforts are directed towards reducing dimensionality and representing unstructured data units as dense vectors in low-dimensional …

Statistical Analysis of Resilience Distribution and Application to Rural Electric Distribution System subjected to Hurricane Wind
… area's large-scale transmission system or networked power delivery system. They are barely applicable to the rural power distribution system, whose intrinsic properties vary distinctively compared to an urban area. These inherent properties such as less robustness due to the high …

Network Design and Analysis Problems in Telecommunication, Location-Allocation, and Intelligent Transportation Systems
… the design and analysis of telecommunication networks, location-allocation distribution contexts, and intelligent transportation networks. Specifically, the corresponding problems addressed in these areas are a local access and transport area (LATA) network design problem, the discrete …

The relationship between journal use in a medical library and citation use
… on the Spearman rank and Pearson correlation tests. The distribution comparison of use and citation age distributions was examined by using Kolmogorov-Smirnov goodness of fit tests. The t-test was used to test the difference of use half-life and citation half-life. Comparisons were also made …

Changes in dietary intakes and cardiovascular disease risk factors in black South Africans from 2005 to 2015 : the PURE-SA-NW study
… Data for PURE-SA-NWP were collected from two communities, one urban and one rural. Baseline data were collected in 2005, with two follow-up collections conducted in 2010 and 2015. Dietary data were collected using a 145-item culturally sensitive quantified food frequency questionnaire …
