Great news!, the ABC paper we had originally started in 2012 in Melbourne with Gael Martin and Brendan MacCabe, before joining forces with David Frazier and Worapree Maneesoothorn, in expanding its scope to using auxiliary likelihoods to run ABC in state-space models, just got accepted in the Journal of Computational and Graphical Statistics. A reason to celebrate with a Mornington Peninsula Pinot Gris wine next time I visit Monash!
weakly informative reparameterisations

Our paper, weakly informative reparameterisations of location-scale mixtures, with Kaniav Kamary and Kate Lee, got accepted by JCGS! Great news, which comes in perfect timing for Kaniav as she is currently applying for positions. The paper proposes a unidimensional mixture Bayesian modelling based on the first and second moment constraints, since these turn the remainder of the parameter space into a compact. While we had already developed an associated R package, Ultimixt, the current editorial policy of JCGS imposes the R code used to produce all results to be attached to the submission and it took us a few more weeks than it should have to produce a directly executable code, due to internal library incompatibilities. (For this entry, I was looking for a link to our special JCGS issue with my picture of Edinburgh but realised I did not have this picture.)
a lifetime word limit…
Posted in Books, Kids, pictures, University life with tags editorial, Nature, predatory publishing, publication on November 20, 2017 by xi'an“Exceptions might have to be made for experts such as statisticians and bioinformaticians whose skills are required on many papers.”
One of these weird editorials periodically occurring in Nature. By Brian Martinson, suggesting that the number of words allotted to a scientist should be capped. Weird, indeed, and incomprehensible that Nature wastes one of its so desperately sought journal page on such a fantastic (in the sense of fantasy, not as in great!) proposal. With sentences like “if we don’t address our own cognitive biases and penchant for compelling narratives, word limits could exacerbate tendencies to publish only positive findings, leading researchers to explore blind alleys that others’ negative results could have illuminated” not making much sense even in this fantasy academic world… As for the real world, the list of impossibilities and contradictions stemming from this proposal would certainly eat all of my allotted words. Even those allotted to a statistician. The supreme irony of the (presumably tongue-in-cheek) editorial is that the author himself does not seem particularly concerned by capping his own number of papers! (Nice cover, by the way!)
