With the LHC coming on line anon, it is appropriate to highlight the Banff Challenge, which was designed as a way to figure out how to place bounds on the mass of the Higgs boson. The equations that were to be solved are quite general, and are in fact the first attempt that I know of where calibration data are directly and explicitly included in the analysis.

The paper about the Banff challenge [0712.2708] and the statistics tutorial for cosmologists [0712.3028] are the personal recommendations from this week’s [arXiv] list. Especially, I’d like to quote from Licia Verde’s [astro-ph:0712.3028],
In general, Cosmologists are Bayesians and High Energy Physicists are Frequentists.
I thought it was opposite. By the way, if you crave for more papers, click Continue reading ‘[ArXiv] 3rd week, Dec. 2007’ »
Dong-Woo, who has been playing with BEHR, noticed that the confidence bounds quoted on the source intensities seem to be unchanged when the source counts are zero, regardless of what the background counts are set to. That is, p(s|NS,NB) is invariant when NS=0, for any value of NB. This seems a bit odd, because [naively] one expects that as NB increases, it should/ought to get more and more likely that s gets closer to 0.
