Along with 17 other Associate Editors, I have just resigned from the editorial board of Statistics and Computing. This was a difficult decision, since it is a great journal, which has published man…

The Rousseeuw Prize for Statistics is a biennial prize to celebrate outstanding contributions to statistics research.

We propose a mathematical formalisation of the ``wave model'' originally developed in historical linguistics but with further applications in human sciences. This model assumes new traits appear in a population and spread to nearby populations depending on their closeness. It is mostly used to describe joint evolution of closely related populations, for example of several dialects. These situations of permanent contact are not accurately represented by its competitors based on tree structures. We built a fully Bayesian generative model where innovation spread along a fixed graph and disappear according to a death process. We then develop a Metropolis-Hastings within Gibbs sampler to sample from the posterior distribution on the graph. We test our method on simulated datasets as well as on several real dataset.

The family tree remains the main metaphor for describing the evolutionary history and relationships of languages. Languages, like biological species, evolve following processes such as descent with m...

In some applied scenarios, the availability of complete data is restricted, often due to privacy concerns; only aggregated, robust and inefficient statistics derived from the data are made accessible....
