John Snow writes: I came across this blog by Milan Shen recently and thought you might find it interesting. A couple of things jumped out at me. It seemed like the so-called ‘Winner’s Curse’ is just another way of describing the statistical significance filter. It also doesn’t look like their correction method is very effective. […]
