This paperĀ is the paper describing how Uri Simonsohn identified academic misconduct using statistical analyses. This approach has received a huge amount of press in the scientific literature. The basic approach is that he calculates the standard deviations of mean/standard deviation estimates across groups being compared. Then he simulates from a Normal distribution and shows that under the Normal model, it is unlikely that the means/standard deviations are so similar.
