How to calculate the number of digits in a standard distribution box
Benford's law also makes predictions about the distribution of second digits, third digits, digit combinations, and so on. Benford's law may be derived by assuming the dataset values are uniformly distributed on a logarithmic scale. The graph to the right shows Benford's law for base 10.OverviewBenford's law, also known as the Newcomb–Benford law, the law of anomalous numbers, or the first-digit. A set of numbers is said to satisfy Benford's law if the leading digit d (d ∈ {1,. , 9}) occurs with The leading digits in such a set thus have the following distribution: The quantity . The discovery of Benford's law goes back to 1881, when the Canadian-American astronomer noticed that in the earlier pages (that started with 1) were much more worn than the other p.
