About Me

I'm Xiaorui (Jeremy) Zhu, an Assistant Professor in the Department of Business Analytics and Technology Management, Towson University. I obtained my Ph.D. degree in Business Analytics from the University of Cincinnati, Lindner College of Business. Before that, I received an master degree in Finance from Penn State University and a master of Applied Statistics from Beijing University of Technology.

My research interests include high-dimensional statistics, categorical data analysis, machine learning, default prediction and sentiment analysis in finance and information systems, and creativity. Specifically, I study the variable selection methods and statistical inference in high-dimensional statistics. One of my works proposed the sparsified simultaneous confidence intervals for the high-dimensional linear regression model (SSCI). In finance, I work on bankruptcy, delisting problems, and stock return prediction using sentiment analysis. For the bankruptcy problem, I am interested in the prediction of bankruptcy and how the bankruptcy risk is associated the equity return. One of my projects focuses on bankruptcy and delistings due to other failure reasons, two closely related yet sharply different distress events. We identify two different models for bankruptcy risk and other-failure risk. In another published work, I proposed an adaptive method to estimate the coefficients of the GARCH model with heavy-tailed innovation. I'm also interested in how creativity can stimulate the development of machine learning algorithms and artificial intelligence.

I believe staying Hungry, Foolish, and Creative is the secret to success. I dream of being a statistician engineering a machine intelligence that is the "epitome" of the descendants of human intelligence.

I'm interested in making research results more intuitive and understandable. Therefore, I use Shiny app for interactively telling interesting data story. Here are some latest shiny apps and R packages I created. Everyone interested in my research or software is welcome to contact me.

SurrogateRsq (R Package)

An R package for the Surrogate \(R^2\) measure for categorical data analysis. It can generate a point or interval measure of the surrogate \(R^2\), and a ranking measure of each variable's contribution.

PAsso (R Package)

An R package and implementation of the unified framework for assessing Parrtial Association between ordinal variables after adjusting for a set of covariates.

SSCI (R Package)

An R Package for constructing the sparsified simultaneous confidence intervals (SSCI).

SPSP (R Package)

An R Package for Selecting the relevant predictors by Partitioning the Solution Paths of the Penalized Likelihood Approach.

Trading Strategies (App)

It is an online platform to display interactive trading strategies.

Stock Display (App)

It is an Shiny app that is used to display time-series data and forecasting of stocks.

Bankruptcy Prediction (App)

It is live app showing probability of bankruptcy of public companies in US.
