While stuck on an airplane in Chicago, I wrote s short note for Genevieve Graves (Princeton), in answer to a question from her about what I would do instead of stacking data, especially if I wanted to see the intrinsic variance among the data as well as the mean. My proposal is related to a Factor Analyzer, which is like a probabilistic form of Principal Components Analysis (and therefore like HMF). I also wrote a bit in my Atlas of Galaxies, which is becoming a bit of an albatross. I am not good at commitment (when it comes to projects, anyway).
