Introduction to Bayesian Methods for Clinical Trial Design and Sample Size Determination
Time: 9 am - 5 pm
Instructors: Matthew A. Psioda & Joseph G. Ibrahim (UNC Chapel Hill)
Abstract: This short course is designed to give biostatisticians and data scientists a comprehensive overview of the use of Bayesian methods for clinical trial design and training on how these methods can be implemented using standard software. Specially, applications of methodology will be demonstrated using R, SAS or both. Part I will give a broad overview of Bayesian sample size determination with a focus on fixed sample size trials either in the phase II or the phase III setting. Focus is paid to four concepts that govern sample size determination: (1) the sampling prior that reflects knowledge about the parameter(s) in the data model, (2) the fitting prior used to analyze data once collected, (3) the criterion used as the basis of sample size determination, and (4) the strategy for monitoring, if the trial will include one or more interim analyses. For (3), a comprehensive review of Bayesian criterion for sample size determination will be given, covering such topics as Bayesian type I error rate control and power, average coverage criterion, average length criterion, and worst outcome criterion. For (4) multiple strategies will be discussed for monitoring accumulating data, including using predictive probability of success and sequential methods. Part II will focus broadly on advanced Bayesian trial designs that incorporate information borrowing. The types of designs considered fall into two broad categories: (1) designs that borrow information through the use of an informative prior specified a priori based on one or more historical datasets, and (2) designs that seek to borrow information across subgroups within a trial. Example designs of type (1) include trials where the goal may be to show that a next-generation medical device (e.g., a coronary stent) is non-inferior or superior to a previous generation of the same device, and designs that seek to extrapolate information on treatment efficacy from adult trials to the pediatric setting. Example designs of type (2) include basket trials where the goal is to make inferences regarding treatment activity for different tumor types in patients whose tumor has a genetic marker targeted by the investigational treatment.


Bayesian Modelling of Epidemics: From Population to Individual-level Models
Time: 9 am - 5 pm
Instructors: Rob Deardon & Caitlin Ward (University of Calgary)
Abstract: With the ongoing COVID-19 pandemic, there has been an understandable increase in the interest in the mathematical and statistical modelling of infectious disease epidemics. Inference for mechanistic models is made more complicated by the fact that we often have latent variables (e.g., infection times). Additionally, we often have complex heterogeneities in the population we wish to account for, since, for example, populations do not tend to mix homogeneously. This often leads to a need for spatial and/or network-based models. The Bayesian framework is ideal for such complex systems, as well as prediction from the models.
In this workshop, we will examine characteristics of, and inference for, such infectious disease models starting with the classic SIR ODE-based model, and expanding into individual-level models. The workshop will include instruction on the use of the R packages, “deSolve”, “adaptMCMC” “EpiILM” and "EpiILMCT”, to implement models and inferential methods.


Bayesian multivariate time series analysis for environmental science and neuroscience
Time: 1 pm - 5 pm
Instructors: Raquel Prado (University of California - Santa Cruz), Marco Ferreira (Virginia Tech)
Abstract: This course covers principles and methods of Bayesian dynamic modeling, focusing on multivariate time series analysis and forecasting, with methodological details of central model classes explored in a range of applications to neuroscience and environmental science. A key focus is on dynamic linear models - structure, inference, forecasting — including stationary and non-stationary time series. Starting with examples of univariate time series analysis, the course extends to linked systems of univariate series defining specific classes of multivariate models, and goes further in multivariate contexts with dynamic factor models and dynamic spatial factor models. Aspects of simulation-based computation—forward simulation for forecasting, direct, approximate and simulation-based forward-backward analysis of state-space models, and MCMC methods for models with parameters and latent states going beyond the linear/Gaussian framework—are included. The course draws on a range of examples such as analysis of troposphere temperature data, multi-channel brain signal analysis, and analysis of brain imaging data.


Using R for Bayesian Spatial and spatio-temporal health modeling
Time: 8 am - 1 pm
Instructor: Andrew B Lawson (Medical University of South Carolina)
Abstract: R is commonly use now for advanced Biostatistical applications. Bayesian spatial and spatio-temporal modeling of health data is an important topic which can be addressed using tools in R. This course is designed for those who want to cover mapping methods, and the use of a variety of software and variants in application to small area health data. The course will include theoretical input, covering selected Bayesian spatial models, but also practical elements and participants will be involved in hands-on in the use of R, BRugs, Nimble, and CARBayes in disease mapping applications. Both spatial health examples will be covered in the course as well as simple space-time modelling. Examples will range over county level respiratory cancer incidence (spatial and spatio-temporal) and Covid-19 space-time modeling in US states. The course would be suitable for those with some R experience, but who have limited experience of spatial modeling in health applications.


Introduction to Bayesian Nonparametric methods for causal inference
Time: 9 am - 5 pm
Instructors: Michael Daniels (University of Florida), Antonio Linero (University Texas Austin), Jason Roy (Rutgers School of Public Health)
Abstract: Bayesian nonparametric (BNP) methods can be used to flexibly model joint or conditional distributions, as well as functional relationships. These methods, along with causal assumptions, can be used with the g-formula for inference about causal effects. This general approach to causal inference has several possible advantages over popular semiparametric methods, including efficiency gains, the ease of causal inference on any functionals of the distribution of potential outcomes, the use of prior information, and capturing uncertainty about causal assumption via informative prior distributions. In this workshop we review BNP methods and illustrate their use for causal inference in the setting of point treatments, mediation, and semi-competing risks. We present several data examples and discuss software implementation using R. The R code and/or packages used to run the data examples will be provided to the attendees at a specific github site.
