Jackie Lambert, "Detecting Fraud Using Benford's Law " , J uly 2006.

Excerpt: Benford's Law, or the First Digit Law as it is sometimes called, states that the first digits of many numbers do not occur randomly and evenly throughout a dataset. Using intuitive logic and the general laws of probability we would assume that the probability of the first digit of a number being 4 and the probability of it being 9 is the exact same with about a 0.111 chance. However, as Benford's Law would have it the probability of the first digit being a 4 is 0.096 and the probability of it being a 9 is 0.045(Nigrini). Why and how does this phenomenon occur and how is this beneficial to us in detecting fraud? <download>
