FIRSTDIGIT: Stata module to analyse first digits of numeric variables

Statistical Software Components from Boston College Department of Economics

Abstract: firstdigit tabulates and analyses the first digits of numeric variables. It also tests Benford's law that digits d = 1,..,9 occur with probabilities log10(1 + 1/d). Thus given data of 12, 345, 6789, etc., it would extract 1, 3, 6, etc., tabulate the frequencies of the digits 1 to 9 and give a chi-square test of the law.
