Minor Description
Benford's Law is a useful analytical tool to determine if a number was generated with a random process by evaluating the relative proportions of the leading digit. It can be used to detect accounting, financial, and election fraud.
Wikipedia's Benford's Law page has a good overview.
Hive is well suited to calculate Benford's Law. The result should be a named struct with names 1-9 and values being the corresponding proportions of each digit.
An alternative is to calculate the deviations from Benford's Law for each digit. The structure of the resulting array would be the same, but the result would be the difference between the actual proportions and the proportions given the by formula on Wikipedia.
