papers that begin with "Let"

I don't write papers that begin with the word "Let". However, today Roweis convinced Bovy and me that our joint paper on the method we use to reconstruct distribution functions from noisy and incomplete data should be closer to that style, if we are going to publish it in the stats literature. We also discussed many other things with Roweis, including operations research algorithms, decision theory, and matrix math. It is always great when we get a visit from the master.
