Title: Non-linear associations between the urban built environment and commuting modal split : a random forest approach and SHAP evaluation
Author: Thill, Jean-Claude, Hatami, Faizeh, Rahman, Md. Mokhlesur, Nikparvar, Behnam
Date Created: 2023
Subjects--Topical: Commuting, Statistics
Description: The study of commuting mode choice is crucial since driving, with all its associated environmental and economic consequences, is the United States' most popular mode of transportation due to urban sprawl, priority to road construction and America'...

Title: MATLAB tool for probability density assessment and nonparametric estimation
Author: Jacobs, Donald J., Farmer, Jenny
Date Created: 2022
Subjects--Topical: Statistics, Entropy
Description: A MATLAB function is presented for nonparametric probability density estimation, based on an iterative method that employs the principle of maximum entropy and characteristic properties of single order statistics. Featuring a robust and adaptive d...

Title: Beyond the PCA : a comprehensive review of dimension reduction techniques
Author: Kenjale, Tanmay
Date Created: 2022
Subjects--Topical: Statistics, Dimension reduction (Statistics), Regression analysis
Description: Regression analysis is a key tool in modeling the relationship between predictor variables and the conditional mean of the response variable. However, as the number of predictors increases, existing estimation methods become challenging. Dimension...

Title: In search of a predictive model for aflatoxin insurance claims based on temperature data
Author: German-Jimenez, Fausto, Terejanu, Gabriel
Date Created: 2022
Subjects--Topical: Computer science, Machine learning, Statistics, Agriculture
Description: Aflatoxin is a carcinogenic product of mold that affects thousands of corn-producing farms in the United States every year, so being able to predict when a county will have compromising aflatoxin levels could be beneficial for insurance companies....

Title: Boosting computational effectiveness in big spatial flow data analysis with intelligent data reduction
Author: Thill, Jean-Claude
Date Created: 2020
Subjects--Topical: Data reduction, Statistics
Description: One of the enduring issues of spatial origin-destination (OD) flow data analysis is the computational inefficiency or even the impossibility to handle large datasets. Despite the recent advancements in high performance computing (HPC) and the read...

Title: Universal sample size invariant measures for uncertainty quantification in density estimation
Author: Jacobs, Donald J., Farmer, Jenny, Merino, Zach, Merino, Zach
Date Created: 2019
Subjects--Topical: Statistics, Entropy
Description: Previously, we developed a high throughput non-parametric maximum entropy method (PLOS ONE, 13(5): e0196937, 2018) that employs a log-likelihood scoring function to characterize uncertainty in trial probability density estimates through a scaled q...

Title: High throughput nonparametric probability density estimation
Author: Jacobs, Donald J., Farmer, Jenny
Date Created: 2018
Subjects--Topical: Statistics, Probabilities
Description: In high throughput applications, such as those found in bioinformatics and finance, it is important to determine accurate probability distribution functions despite only minimal information about data characteristics, and without using human subje...

Title: Statistical measures to quantify similarity between molecular dynamics simulation trajectories
Author: Jacobs, Donald J., Farmer, Jenny, Kanwal, Fareeha, Nikulsin, Nikita
Date Created: 2017
Subjects--Topical: Molecular dynamics, Statistics
Description: Molecular dynamics simulation is commonly employed to explore protein dynamics. Despite the disparate timescales between functional mechanisms and molecular dynamics (MD) trajectories, functional differences are often inferred from differences in ...

Title: Heterogeneous crowd-sourced data analytics
Author: Thill, Jean-Claude
Date Created: 2017
Subjects--Topical: Data mining, Statistics
Description: Advances in computing, communication, storage, and sensing technologies have reshaped the lives of people by changing the way they live, work, interact with their environments, and even socialize. Modern information systems collect valuable inform...

Title: Changes in Lysozyme flexibility upon mutation are frequent, large and long-ranged
Author: Jacobs, Donald J., Verma, Deeptak, Livesay, Dennis R.
Date Created: 2012
Subjects--Topical: Bioinformatics, Statistics
Description: We investigate changes in human c-type lysozyme flexibility upon mutation via a Distance Constraint Model, which gives a statistical mechanical treatment of network rigidity. Specifically, two dynamical metrics are tracked. Changes in flexibility ...

Title: Best probability density function for random sampled data
Author: Jacobs, Donald J.
Date Created: 2009
Subjects--Topical: Statistics, Probabilities
Description: The maximum entropy method is a theoretically sound approach to construct an analytical form for the probability density function (pdf) given a sample of random events. In practice, numerical methods employed to determine the appropriate Lagrange ...
