About Me

I'm Xiaorui (Jeremy) Zhu, a Ph.D. candidate at the University of Cincinnati, Lindner College of Business. My major is Business Analytics. Before coming to the University of Cincinnati, I received an MS in Finance from Penn State University and a master of applied statistics from Beijing University of Technology.

My research interests include high dimensional statistics, machine learning, finance, relevant applications, and creativity. In high-dimensional statistics, I study the variable selection methods and the post-selection inference. One of my works proposed the sparsified simultaneous confidence intervals for the high-dimensional linear regression model (SSCI). In machine learning, I study robust estimation methods when data have missing values or contaminations. In finance, I work on volatility models and bankruptcy problems. In a published work, I proposed an adaptive method to estimate the coefficients of the GARCH model with heavy-tailed innovation. For the bankruptcy problem, I am interested in the prediction of bankruptcy. One of my projects focuses on the relationship between bankruptcy risk and stock returns. How creativity can stimulate the development of machine learning algorithms and artificial intelligence always arouse my interest.

I believe that stay Hungry, stay Foolish, and stay 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.

Software

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 package I created. Everyone interested in my research or software is welcome to contact me.

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.

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.

Forecasting and Time Series Methods
Instructor

This is a course in the analysis of time series data with emphasis on appropriate choice of models for estimation, testing, and forecasting. It covers Univariate Box-Jenkins for fitting and forecasting time series; ARIMA models, stationarity and nonstationarity; diagnosing time series models; forecasting: point and interval forecasts; seasonal time series models; modeling volatility with ARCH, GARCH; modeling time series with trends; and other methods. The R Shiny App development will be covered to help students obtain skills of making prototype of their models and ideas.
