We [Julien and myself] are quite pleased to announce that

  • the scientific committee for the workshop has been gathered
  • the webpage for the workshop is now on-line (with a wonderful walrus picture whose author we alas cannot identify)
  • the workshop is now endorsed by both IMS and ISBA, which will handle registration (to open soon)
  • the reservation of hotel rooms will be handled by Hurtigruten Svalbard through the above webpage (this is important as we already paid deposit for a certain number of rooms)
  • we are definitely seeking both sponsors and organisers of mirror workshops in more populated locations

As an item of trivia, let me recall that Svalbard stands for the archipelago, while Spitsbergen is the name of the main island, where Longyearbyen is located. (In Icelandic, Svalbarði means cold rim or cold coast.)

Takaisin helsinkiin

I am off tomorrow morning to Helsinki for the European Meeting of Statisticians (EMS 2017). Where I will talk on how to handle multiple estimators in Monte Carlo settings (although I have not made enough progress in this direction to include anything truly novel in the talk!) Here are the slides:

I look forward this meeting, as I remember quite fondly the previous one I attended in Budapest. Which was of the highest quality in terms of talks and interactions. (I also remember working hard with Randal Douc on a yet-unfinished project!)

On my (uneventful if rather long) flight to Salt Lake City yesterday, I had the great privilege to fly over a cloudless Greenland and I managed to take a few pictures (with the help of fellow passengers sitting on the other aisle)… The light was terrific as most of the trip was in a permanent sunset (since we were flying way up North!).

I actually had a bit of a fright thanks to my RER train being delayed (surprise!) but for whatever reason Charles de Gaulle airport was almost deserted and I went through all steps in less than the ten minutes I was allowed before they closed the gates (which was also the time it took me to get from the plane to the car rental desk in Salt Lake City!). As my laptop went out of battery very quickly by not suspending properly (!), I managed to read and review three papers on ABC and to start Persi’s book on Magic and Mathematics (which reads very well, even after nine hours in a plane!).

As I was seating on an exit row, I got a leaflet explaining that I should read the instructions, and be ready to “assess, select, and follow a safe path away from the emergency exit” (model choice at work!). Among people prevented from sitting in an exit row, those “requiring the use of a seat belt extension” (only “to preclude the hazard of entanglement with the additional length of the extension by those passengers attempting to expeditiously exit the aircraft”, which sounds both like a short story and legalist caution against discrimination lawsuits!) and those “travelling with an emotional support animal, service animal  or family pet” (which again sounds very descriptive for no clear reason, but again hint at some past story requiring the distinction between those different kinds of pets!).
