Applied Linear Regression (STAT3200)

University of Iowa

Jan 2023 – May 2023 Iowa City, Iowa
This course focuses on applications and hands-on data analysis with computer software (primarily R). A list of the topics to be covered include:

  • examining and transforming data
  • simple, multiple, and dummy variable regressions
  • one-way ANOVA
  • multicollinearity
  • diagnostics of influential data
  • generalized linear models including logistic regression
  • interpretation and presentation of analysis results

Introduction to Data Science (STAT1015, new course)

University of Iowa

Aug 2021 – Dec 2021 Iowa City, Iowa
This course is intended for lower-level undergraduate students. The goal is to prepare students with the necessary knowledge and useful skills to tackle real-world data analysis challenges. This course will cover basic statistical concepts and computing skills in the field of data science. A list of the topics to be covered include:

  • R basics (importing data, data types, sorting, and summarizing)
  • data visualization with ggplot2, robust summarises
  • intro to probability, statistical inference, and regression models
  • intro to machine learning (classification, clustering, and prediction)

Mathematical Statistics II (STAT4101)

University of Iowa

Jan 2021 – May 2023 Iowa City, Iowa
This course is a continuation of STAT4100. It is intended for upper-level undergraduate students in the mathematical sciences as well as for graduate students in all disciplines. The goal is to give students a solid foundation in the theory and methods of statistical inference. The main topics include:

  • point estimation and confidence intervals
  • convergence in distribution and convergence in probability
  • maximum likelihood methods
  • sufficient statistics
  • hypothesis testing

Mathematical Statistics I (STAT4100)

University of Iowa

Aug 2020 – Dec 2022 Iowa City, Iowa
This is a course in mathematical statistics intended for upper-level undergraduate students in the mathematical sciences as well as for graduate students in all disciplines. The goal is to provide a solid foundation in the theory of random variables and probability distributions.

  • Probability and distributions (sets, random variables, expectation, important inequalities)
  • Multivariate distributions (joint/marginal distributions, transformation, independence)
  • Some special distributions (Binomial, Negative Binomial, Geometric, Poisson, Normal)
