Title: Abstract visualization of large-scale time-varying data
Author: Yu, Li
Date Created: 2012
Description: The explosion of large-scale time-varying datasets has created critical challenges for scientists to study and digest. One core problem for visualization is to develop effective approaches that can be used to study various data features and tempor...

Title: Analysis of Baseball Pitching: An Investigation of Shoulder Rotational Properties, Biomechanics, and Injury
Author: Stokes, Hannah
Date Created: 2023
Subjects--Topical: Biomechanics

Title: Analysis of failure time data with missing and informative auxiliary covariates.
Author: Ghosh, Lipika
Date Created: 2011
Description: In this dissertation we use Cox's regression model to failure time data with continuous informative auxiliary variables in the presence of a validation subsample. The work is motivated by a common problem of missing or mismeasured covariates in su...

Title: Asymptotic Normality of Entropy Estimators
Author: Zhang, Xing
Date Created: 2013
Description: Shannon's entropy plays a central role in many fields of mathematics. In the first chapter, we present a sufficient condition for the asymptotic normality of the plug-in estimator of Shannon's entropy defined on a countable alphabet. The sufficien...

Title: NONPARAMETRIC PREDICTIVE REGRESSION
Author: Yu, Xintian
Date Created: 2016
Description: In ﬁnancial time series nonlinear eﬀects and time-varying eﬀects are observed. In this dissertation we propose a predictive regression model with time varying coeﬃcients and functional coeﬃcients. It allows for nonstationary predictors. We establi...

Title: Non-nested Model Selection via Empirical Likelihood
Author: Zhao, Cong
Date Created: 2017
Description: In this dissertation we propose an empirical likelihood ratio (ELR) test to conductnon-nested model selection. It allows for heteroscedasticity and works for any twosupervised statistical learning methods under mild conditions. We establish asympt...
