Doing Bayesian Data Analysis


Instructor: John KruschkeOffered through the

Many fields of science are transitioning from null hypothesis significance testing (NHST) to Bayesian data analysis. Bayesian analysis provides complete information about the relative credibilities of all candidate parameter values for any descriptive model of the data. Bayesian analysis applies flexibly and seamlessly to complex hierarchical models and realistic data structures, including small samples, large samples, unbalanced designs, missing data, censored data, outliers, etc. Bayesian analysis software is flexible and can be used for a wide variety of dataanalytic models. The course shows you how to do Bayesian data analysis, hands on (with free software called R and JAGS). The intended audience is advanced students, faculty, and other researchers, from all disciplines, who want a groundfloor introduction to doing Bayesian data analysis. No mathematical expertise is presumed.

This course is offered through the University of St. Gallen Summer School in Empirical Research Methods, so you must register to attend. Late registration will be allowed for a limited time. Complete registration and contact information is at this link. The instructor has no control of fees or registration procedure.
You are encouraged to bring a notebook computer to the workshop, so you can run the programs and see how their output corresponds with the presentation material. If you want to bring a notebook computer to the workshop, please install the software before arriving at the workshop. For complete installation instructions, please refer to this blog entry.
Who is the instructor? John Kruschke is seventime winner of Teaching Excellence Recognition Awards from Indiana University, where he is Professor of Psychological and Brain Sciences, and Adjunct Professor of Statistics. He has written an introductory textbook on Bayesian data analysis; see also the articles linked above. His research interests include the science of moral judgment, applications of Bayesian methods to teaching and learning, and models of attention in learning, which he has developed in both connectionist and Bayesian formalisms. He received the Troland Research Award from the National Academy of Sciences. He is action editor for the Journal of Mathematical Psychology, and is on the editorial boards of Psychological Review, the Journal of Experimental Psychology: General, among others.
Why go Bayesian? Sciences from astronomy to zoology are changing from 20thcentury nullhypothesis significance testing to Bayesian data analysis, because Bayesian analysis provides complete information with flexible application to numerous models. Read more:

Bayesian data analysis is not Bayesian modeling of cognition. Data analysis involves "generic" descriptive models (such as linear regression) without any necessary interpretation as cognitive computation. The rational way to estimate parameters in descriptive models is Bayesian, regardless of whether or not Bayesian models of mind are viable. The concepts and methods of Bayesian data analysis transfer to other Bayesian models, including Bayesian models of cognition. Read more at this blog entry.
