Title: Non-parametric Estimation of Information-theoretic Quantities in Entropic Perspective
Author: Zhang, Jialin
Date Created: 2019
Subjects--Topical: Statistics
Description: Introduced by Shannon, mutual information is a fundamental brick of information theory for its essential role in measuring association on non-ordinal alphabets. Mutual information being zero is a golden property as it indicates a probabilistic ind...

Title: OPTIMAL STRATEGIES IN "LOCKS, BOMBS AND TESTING" (LBT) PROBLEM FOR THE CASE OF INDEPENDENT PROTECTION
Author: Liu, Li
Date Created: 2019
Subjects--Topical: Mathematics, Statistics, Operations research
Description: This thesis constructs a Defense/Attack resource allocation model. Defender uses "locks" to protect their boxes from Attacker, and Attacker uses "bombs" to destroy as many boxes as possible. The first models of such type were given by E. Borel (19...

Author: Zhang, Meijiao
Date Created: 2018
Subjects--Topical: Statistics
Description: The Least absolute deviation combined with the Least absolute shrinkage andselection operator (LAD-LASSO) estimator can do regression shrinkage and selectionand is also resistant to outliers or heavy-tailed errors which is proposed in Wang etal. (...

Title: SEVERAL STATISTICAL RESULTS UNDER MULTINOMIAL DISTRIBUTION WITH INFINITE CATEGORIES
Author: Zhou, Jun
Date Created: 2009
Subjects--Topical: Statistics, Mathematics
Description: This dissertation discusses several statistical results under multinomial distribution with infinite categories. Firstly, the discussion focuses on Simpson's diversity index and Turing's formula. We established an unbiased estimate for the newly p...

Title: STATISTICAL ANALYSIS OF MARK-SPECIFIC PROPORTIONAL HAZARDS MODEL
Author: Li, Mei
Date Created: 2011
Subjects--Topical: Statistics
Description: Competing risks occur frequently in survival analysis, and in some cases, the competingrisks are not discrete. In this dissertation, we develop some statistical inferences to analyzecontinuous competing risks.In Chapter 2, inspired by the HIV vacc...

Date Created: 2018
Subjects--Topical: Management, Statistics, City planning
Description: Parking is a significant facet of the urban transportation system, with a collective revenue of nearly $30 billion in the United States by the end of 2018. Motivated by the inter-temporal demand and supply imbalance as well as the sub-optimal park...
