    Bayesian hypothesis testing

    I'm a PhD student at the Department of Psychological Methods and Statistics at University of Amsterdam with Eric-Jan Wagenmakers. My research focuses on Bayesian hypothesis testing for structural equation models. At the moment the prior is set to the improper null measure, which isn't really a measure.
