The company announced in February 2014 that they had found evidence of Benford's Law appearing in house price data. The claim asserts that the first digit of the set of house prices follows a probability mass function where 1 is the leading digit on a third of the data set, with 9 being the leading digit on only 5% of the house price data set.
The company's announcement also claims to have seen evidence of this law in the distribution of the number of properties in the inventory of each branch.
