Benford's law Wikipedia

1. A set of numbers is said to satisfy Benford's law if the leading digit d (d ∈ {1, ..., 9}) occurs with probability 1. P ( d ) = log 10 ⁡ ( d + 1 ) − log 10 ⁡ ( d ) = log 10 ⁡ ( d + 1 d ) = log 10 ⁡ ( 1 + 1 d ) {\displaystyle P(d)=\log _{10}(d+1)-\log _{10}(d)=\log _{10}\left({\frac {d+1}{d}}\right)=\log _{10}\left(1+{\frac {1}{d}}\right)} The leading digits in such a set thus have the following distribution: The quantity P ( d ) {\displaystyle P(d)} is proportional to the space between d and d + 1 on a logarithmic scale. Therefore, this is the distribution expected if the logarithms of the numbers (but not the numbers themselves) are uniformly and randomly distributed. For example, a number x, constrained to lie between 1 and 10, starts with the digit 1 if 1 ≤ x < 2, and starts with the digit 9 if 9 ≤ x < 10. Therefore, x starts with the digit 1 if log 1 ≤ log x < log 2, or starts with 9 if log 9 ≤ log x < log 10. The interval [log 1, log 2] is much wider than the interval [log 9, l...

Benford’s Law. Take a collection of seemingly random numbers, for instance the gross domestic product of 212 countries, and then examine the leading digit. For instance, for the number $435 million (the 2015 GDP of Tonga) the leading digit is 4. The leading digits will of course be from 1-9, since 0 cannot be a leading digit.

Does Benford's law apply to prime numbers?

1. The answer to our question clearly depends on where the prime numbers come from. It is very difficult to quantify the instructions "pick a random integer" or "pick a random prime" in a way in which satisfies the most basic laws of probability. To see what we mean let A and B be subsets of the positive integers N. If P(A) is the probability that the "random" integer we pick is in the set A, then we would need that Now if each integer is equally likely, we then have so P( {1} ) < 1/n for every integer n. The probability of picking any one integer (hence any set of integers), would have to be zero! So when we say "pick a random integer" we can not pick from the whole set of positive integers with each integer being equally likely. (See [Raimi1969] and [Raimi1976] for a deeper discussion of these issues and Benford's law.)

Using Spreadsheets and Benfords Law to Test Accounting Data

1. Take the case of someone who wants to evaluate corporate purchase invoices—a popular target of corporate abuse. Although the amount of information contained in each invoice is likely to be considerable, this example will focus only on the purchase amounts. The goal of applying Benford’s Law here is to know how “natural” such transactions are. Step 1: Select the Sample Data The first task is to obtain sample test data and store them in an Excel spreadsheet—the more observations included, the better. Using the data for a complete year is best, but if the number of items is large, smaller samples are permissible. For statistical reasons, however, there should be at least 100 observations. Step 2: Parse the Lead Digit As noted previously, Benford’s Law focuses on the lead digit in sets of naturally occurring numbers. The actual magnitude of the data (i.e., whether an amount is $10, $100 or $1,000) is unimportant. In a spreadsheet, one can select or “parse” the lead digit for each dollar...

The Benford’s Law Hustle™ NoahSD's Awesome Poker Blog

1. Do a quick experiment for me: Open a random article in Wikipedia by clicking here. (I didn’t doctor that link or anything, but if you don’t trust me, feel free to navigate to Wikipedia the old-fashioned way. The random article link can be found on the left of any article’s page.) Find the first number in the article and remember its first digit. (If there isn’t a number, go to another random article.) Repeat this three times. The vast majority of you will have been a one or a two. Only about one in six of you will have seen an eight or a nine. Weird, huh? However, there’s also a pretty good chance that you noticed a gimmick when you did that, and you might think you figured this out. If you didn’t, check out the Wikipedia page for the Nobel Prize in Physics. The first number in that article is 1895, which does indeed start with a one, but, it’s a year. Wikipedia probably references a lot more years after the year 1000 than before the year 1000, so of course years appearing on Wikipe...

How do you use Benford's law to spot Fraud?

WHEN TO USE BENFORD'S LAW TO SPOT FRAUD. Briefly explained, Benford's Law maintains that the numeral 1 will be the leading digit in a genuine data set of numbers 30.1% of the time; the numeral 2 will be the leading digit 17.6% of the time; and each subsequent numeral, 3 through 9, will be the leading digit with decreasing frequency.

How do you apply Benford's law to frequency distribution?

To apply Benford’s Law, therefore, an accountant must count the number of times a 1 appears as the lead digit in the data values, the number of times a 2 appears, etc., and then examine the resulting frequency distribution. The distribution is “natural” if it follows Benford’s distribution, and suspect otherwise.
