Abstract

Benford’s law gives expected patterns for frequencies of digits in numerical data sets according to their position in numbers. Benford’s law is known as a ‘first digit law’, ‘digit analysis’ or ‘Benford-Newcomb phenomenon’. Based on Benford’s law tests for leading and non-leading and appropriate groups of digits have been derived. Practical problem is how to test conformity to this law. In this paper, variant of Wilcoxon test, which can be used both for frequencies and sums of significands, is proposed.
