LGM 2012, Trondheim (3)
Last and final day of LGM 2012: it started most auspiciously with a bit of melted snow. The big news of the day however was [for me] that the next LGM was staged to take place in Reykjavik, Iceland. Indeed, Iceland is sharing top-of-the-list with Greenland and Patagonia for the countries I want to visit, one day, and I hope I will be able to attend and to take some time off to make a trek inland… Besides this personal (and therefore uninteresting!) happy event (!), the day contained a wealth of interesting talks, from Malgorzata Roos talking about using Hellinger distance to evaluate prior sensitivity (with the side impact of driving me posting a question on StackExchange about unbiased estimators of Hellinger distances!), to Aki Vehtari discussing cross-validation and other predictive entities (and concluding on the poor performances of DIC), to Luke Bornn proposing using auxiliary variables and warping to recover stationarity, to Alex Lenkoski achieving a fairly compelling advance by noticing that Gaussian graphical model selection can be handled outside the reversible jump framework, and more (including a machine-learning talk by Valeria Vitelli, now a next door neighbour at École Centrale, on the other side of Parc de Sceaux!). The conclusion talk by Gregor Gorjanc on statistical models for animal breeding genetics was more historical than methodological, however it should work as a nice refresher each time I need to make sure I understand the genetic vocabulary!
All in all, this was a wonderful workshop! New topics that I hope to study deeper, new people I was lucky to meet, most enjoyable city and running routes, hence a highly consistent choice of LGM meeting locations!, a superb sunset on the Trondheimsfjord the last evening, terrific breakfasts that border brunches, convenient travel connections (except for the last leg on the RER train from Charles de Gaulle where I got stuck for one hour)… Just great.
