This is a first course in Bayesian statistical analysis for graduate students in biostatistics. The fundamentals of Bayesian inference are introduced, including Bayes’ Theorem and prior and posterior distributions. Bayesian inference is compared and contrasted with frequentist methods through application to common problems in biostatistics. Inference based on conjugate families, as well as a computation-based introduction to Markov chain Monte Carlo methods is presented. Bayesian regression models are introduced, including model checking and selection, followed by an introduction to Bayesian hierarchical regression models. The course format emphasizes applied data analysis and is more heavily weighted toward heuristics and computation-based exploration of Bayesian methods rather than an intense mathematical treatment. Students should have a working knowledge of probability theory, likelihood, and applied frequentist data analysis including linear and logistic regression, and an understanding of how calculus is used in biostatistical applications. Prerequisite: None. Credits: 3
This course will teach students how to analyze biomedical data from a Bayesian inference perspective with a strong emphasis on using real-world data, including electronic health records, wearables, and imaging data. This is a second course in Bayesian inference and will start by introducing the hierarchical model as a flexible framework for analyzing complex data structures. This includes missing data, and spatial and longitudinal data. Then Bayesian machine learning approaches will be introduced, including regularization for high-dimensional data and scalable inference techniques for big data, including variational inference. Additional topics may be discussed from the Bayesian perspective, including causal inference, meta-analysis, and time-to-event data. While an applied course, the methods will be introduced from a mathematical perspective, allowing students to obtain a fundamental understanding of the introduced models. Students will learn computational skills for implementing Bayesian models using R and Stan. By the end of this course, students will be well-equipped to tackle complex problems in biomedical research using Bayesian inference.
