The paper was full of much rhetoric but when it finally got to a real argument it picked artificial district sizes in a simulation--which seems ridiculous if they were really interested in simulating real life. From their description of their simulation: " "Our
      simulations, though, consist of two types. In the first type, we simulate an election by creating 1000
      districts wherein each contains the same fixed number of eligible voters. Here we run several sequences
      of elections where every district contains 1000 eligible voters, elections where every district contains
      10,000 voters, and elections where every district contains 20,000 voters".

    You can do the same analysis for the population count of the US states and will get a similar “fraudulent” looking histogram.

    From a Statistician:
    The sample size you're using for this data analysis is way too small. I did this myself using the coronavirus cases for every county in the United States and found that the data follows Benford's Law almost perfectly. Another condition of Benford's Law that is being violated is that you have to have a data set that spans a large number of values. In this case, you have a very high preponderance of cases that fall in the Tens of Thousands and Hundreds of Thousands. I can link the data sheet if anyone is interested.

In other words does benfords law not hold for smaller sample sizes, even if the sample is truly randomised? Or would the conformity just not be as pronounced as a larger sample size?

    To everyone asking for a thorough Benford’s Law analysis of the Chicago precinct election results, the mathematician Matt Parker did a thorough look on his CZcams channel Stand-up Maths.
    The long and short of it is that Benford’s Law is not suitable for all data sets. Specifically, it’s a good indicator only for datasets that span multiple orders of magnitude. Consider a dataset that follows a normal (bell curve) distribution. If, for example, all of these data are one-digit numbers, then the Benford’s Law graph would be equivalent to a histogram of the data; it would look like a bell curve, which doesn’t match Benford’s Law. This doesn’t mean the data is fraudulent, it just means that it doesn’t cover a wide enough range for Benford’s Law to be applicable. A real-world example of this would be the distribution of adult heights in inches- all of the data will be two-digit numbers, so plotting all of the first digits is the same as just grouping all of the data into 10-inch bins. Legitimate data, doesn’t follow Benford’s Law.
    The issue with the Chicago precincts is twofold: first, 98% of the precincts had vote totals between 100 and 1000 (average of 516, stdev of 173) and second, Biden was the favorite in the majority of the precincts. This means that the vast majority of Biden vote totals were three-digit numbers, while about 30% of Trump vote totals were three-digit numbers with 70% as two- or one-digit numbers. This means that, like in the example above, the Biden graph of the data is essentially a histogram with a bin size of 100, which we would reasonably expect to follow a normal distribution, which we see. Meanwhile the Trump data significantly covers three orders of magnitude, making it a suitable dataset for Benford’s Law.

      As the only detraction is that certain areas tend a little bit towards certain leading digits, but not enough that a benfords law with a large data set would fail to follow the general trend. It is only a distinction that matters if you are looking at very minor deviations from benfords law, it doesn't apply to massive deviations.
      You just get the curve being a little steeper or a little less steep, the general curve still exists.

      If the number 6 has the second-highest frequency, then it probably means that the data is not random or the sample size is not large enough. When our analysis comes up with the number 6 as the second-highest frequency, it’s usually telling us that the data is manipulated and probably fraudulent.

    A good video, but I gotta say that Covid data looked like it conformed pretty well with Benford's Law. There are only a few dozen data points, which is not many when you have nine slots to fill with data. Obviously, 1 is going to be the number that starts to take shape first as you add data and produce the Benford graph. 2 will be the second quickest slot to take it's proper shape. In this data, 1 occurs most frequently and 2 is already in the 2 spot. The rest of the graph deviates, but not wildly, and there are limited data points.
    I think the Covid data follows the rule decently well.

    Mr. Bonavito, for data to look suspicious, what ratio between observed and expected should I use as threshold? For instance, if +/- 25% is the fraud threshold, and the "1"s are outside of +/- 25% of the expected 0.3 (higher than 0.0375 or lower than 0.0225), then I would view the data as suspicious.

    • @tomp4925
      @tomp4925 Před rokem

      You had a keen observation.
      Mr Bonavito used "eyeball" analysis.
      The histogram did not look Benford was his conclusion.
      You want a more quantitative analysis.
      There are many, many ways to measure Benford quantitatively. The most common is the Chi Square test.
      You asked for a ratio that deviates from the expected value. You are on the right track because it is an excellent test but unfortunately there is no simple ratio. You would have to calculate the Z score for all 9 digits.
      To be 95% confident that Mr.Bonavito's example DOES NOT follow Benford the Z score should be greater than 2.56(because 9 digits are being tested the Bonferoni adjustment comes in to play).
      I calculated the Z score for 3 digits and not any was over 2.56.
      An example to calculate the Z score for leading digit 1 is:
      (.41-.30)/((.30x.70)/56)^.5= 1.8
      .41 is the actual percentage
      .30 is the expected percentage
      .70 is 1 minus the expected percentage
      56 is the sample size
      ^.5 is the square root
      All 9 digits can be tested that way using each digits own specific actual and expected percentages.
