"An introduction to Bayesian data analysis" will be presented by John K. Kruschke, Professor of Psychological & Brain Sciences, and Adjunct Professor of Statistics, Indiana University.

Abstract:
Bayesian methods have garnered huge interest in cognitive science as an approach to models of cognition and perception. On the other hand, Bayesian methods for data analysis have not yet made much headway in cognitive science against the institutionalized inertia of 20th century null hypothesis significance testing (NHST). Ironically, specific Bayesian models of cognition and perception may not long endure the ravages of empirical verification, but generic Bayesian methods for data analysis should eventually dominate. It is time that Bayesian data analysis became the norm for empirical methods in cognitive science. This talk reviews a fatal flaw of NHST and introduces the audience to some benefits of Bayesian data analysis. The talk presents illustrative examples of multiple comparisons in Bayesian ANOVA and Bayesian approaches to statistical power.
