Students will obtain hands-on experience in implementing a wide range of commonly used statistical methods with real data from public health and biomedical research using the statistical programming language R. The course motivates statistical reasoning and methods through real health data. The focus of the course is to train students in refining a scientific question into a statistical framework, choosing proper regression models, writing scripts and executing them in R, and interpreting scientifically meaningful findings.

690P: Topics in Biostatistics and Data Science

Primary Audience: MS Biostatistics, MS/PhD Epidemiology

The course introduces advanced central topics in biostatistics and health data science including maximum likelihood inference, survival analysis, design and analysis of clinical trials, models for correlated data, bayesian modeling, and causal inference. The course motivates statistical reasoning and methods through substantive research questions and features of data typically available in public health and biomedical research. Students will obtain hands-on experience in applying selected methods on real data using the statistical programming language R. 

683: Introduction to Causal Inference in a Big Data World

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

With the recent and ongoing 'data explosion', methods to delineate causation from correlation are perhaps more pressing now than ever. This course will introduce a general framework for causal inference: 1) clear statement of the scientific question, 2) definition of the causal model and parameter of interest, 3) assessment of identifiability, 4) choice and implementation of estimators including parametric and semi-parametric methods, and 5) interpretation of findings. The methods include G-computation, inverse probability weighted (IPW), and targeted maximum likelihood estimation (TMLE) with Super Learning, an ensemble machine learning method. Students gain practical experience implementing these estimators and interpreting results through discussion assignments, R labs, R assignments, and a final project.

690T: Applied Statistical Genetics

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

This course will provide fundamental statistical concepts and tools relevant to the analysis of high-dimensional genomics data arising from population-based association studies.  A first-course in statistics is assumed.

730: Applied Bayesian Statistical Modeling

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

Bayesian modeling approaches provide natural ways for researchers in many disciplines to structure their data and knowledge, and they yield direct and intuitive answers to scientific questions. In this course, students will learn how to construct Bayesian models to relate (potentially complex) data to scientific questions, to fit such models fitting using statistical programs (R, JAGS and;or STAN), to interpret model results and lastly, to check model assumptions. Specific methods covered will include Bayesian linear and logistic regression, as well as hierarchical (regression) models. Additional topics (survival analysis, time series analysis, spline regression models) will be discussed as time allows. The class also includes the discussion of selected papers from the literature that serve as case studies of Bayesian analyses in public health, as well as a project in which students carry out Bayesian modeling for a real data set.

740: Analysis of Mixed Models Data

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

In many applications, one of the key assumptions foundational to statistical analysis is violated: the assumption of statistical independence. That is, in life, observations often have some amount of dependence among them. This course mainly explores mixed models, one key method that accommodates correlated data.  Other approaches will be touched on briefly. In this course you will learn what the implications of correlated data are, from a statistical perspective, how to think about them, how to analyze them and interpret the data analysis, and the theoretical underpinnings of the data analysis approaches. Learning this material will suit you for professional environments in which you might encounter this kind of data, which are legion. You will also reinforce your data management skills in SAS and R. By the end of this course, students will 1) recognize correlated data occurring by design or chance; 2) diagnose the likely effects of ignoring correlation in data analysis; 3) discuss correlated and longitudinal data; 4) learn about mean models for longitudinal data; 5) learn about mixed modesl; and 6) understand the theoretical bases of the methods employed.

743: Analysis of Categorical Data in Public Health

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

This course provides an overview of statistical methods for analyzing data where the outcome variable is categorical or discrete. The course will emphasize the theoretical underpinnings of the methods as well as an applied understanding of the computation and interpretation, both of which are necessary to succeed with real data analysis. We will cover inference for binomial and multinomial variables with contingency tables, generalized linear models, logistic regression for binary responses, logit models for multiple response categories, log-linear models, some statistical machine learning approaches, inference for matched-pairs, and correlated, clustered data. Examples will be taken from public health and biomedical research.

748: Applied Survival Analysis

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

The aim of this course is to provide students with a strong foundation in statistical techniques used for the analysis of time-to-event data.  Specific topics will include types of censoring mechanisms, graphical and numerical description of survival data, methods for comparison of survival between groups, models to explain and predict survival as a function of baseline and time-varying covariates. Advanced topics including the analysis of competing risks and recurrent event data will be introduced as time permits.  The course will include hands-on analysis of datasets using standard statistical software R.

749: Statistical Methods in Clinical Trials

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

The aim of this course is to provide students with a strong foundation in statistical techniques used for the design, analysis and interpretation of clinical trials. Topics include types of clinical research, study design, treatment allocation, randomization and stratification, quality control, sample size requirements, patient consent, introduction to survival analysis and interpretation of results from clinical trials. Special topics introduced include group sequential methods in clinical trials, including hypothesis testing (one-sided, two-sided and equivalence tests), analysis techniques in the context of sequential trials (repeated confidence intervals) and an introduction to flexible monitoring approaches. Statistical software (SAS/R) will be introduced as needed.

750: Applied Statistical Learning

Primary Audience: MS/PhD Biostatistics, MS/PhD Epidemiology

The goal of this course is to introduce some statistical modeling approaches, which have been developed in the last few years and are widely used in medical and public health research, but are not covered in the core courses of the MS;PhD programs in Biostatistics and Epidemiology. Topics include penalized regression, methods for classification, evaluation of predictions, and robust regression. The cross-validation and bootstrapping procedures, which are important in evaluating and performing inference for models, will be introduced. The course emphasizes helping students to understand the concepts and ideas of some modern statistical methods and apply these methods to research medical and public health studies. Implementation of different methods with R software will be introduced whenever appropriate.

790A: Advanced Statistical Inference
