International Summer School: Introduction to Bayesian Statistics 15.-19. Sept 2014, Bergen, Norway

Since a few years, various subsamples of Jörn Pagel, Joseph Chipperfield, Björn Reineking and I have been teaching an introductory summer school in Bayesian statistics. In previous years, we were in Bayreuth 2011 Bayreuth 2012, Göttingen 2013 and Freiburg 2013. This year, we will be in a beautiful field station close to Bergen, Norway. The…

Should we refer to stochasticity as “error”?

I have been musing about the use of the wording “error” in statistical analysis – it is common to speak about “observation error” or “process error”, but what we really mean are unobserved ecological or physical processes that affect our system or our observations, and that we choose to subsume in a probabilistic model.

Correlation and process in species distribution models: bridging a dichotomy

In a new study led by Carsten Dormann and Stanislaus Schymanski which I coauthored, we look at differences, but also at growing similarities between rather static/statistical/correlative and rather dynamic/process-based approaches to species distribution modeling. I think this is an interesting paper which touches upon a lot of issues that arise from the fact that classical…
