statistical counterpart association

Partly with the help of Roweis, I devised a scheme by which Schiminovich and I can determine the joint distribution of GALEX and SDSS properties of stars and galaxies, without being sure which positional coincidences are true associations across the two surveys, and which are by chance. This falls into the realm of statistical counterpart association, and it involves jointly modeling the true-match and chance-match distributions and a probability (of being a true match) for each coincidence. I started to code it up on the plane home from San Francisco.
