Benford Package

benford.benford module

Benford’s Law applied to files sizes on a local hard drive.

Note: this is a ‘hacky’ version - it works but is NOT very Pythonic

class benford.benford.BenfordDigit(experiment_name, digit_position)

Bases: object

Tests whether given number digits adhere to Benford’s Law.

__experiment_name

string – Unique label for each Benford test

__digit_position

int – significand = 1, 2nd digit, counting from LHS = 2, etc

__digit_count

dict – Tally of numbers encountered in given digit position

__current_number

int – Most recent number reported in digit position, used to increment the corrsponding entry in digit_count tally

__number_count

int – Sum of all numbers found in a given digit_position

__digit_percent

list – List of percentages corresponding to relative frequencies for each number for a given digit_position (1-9 for significand, or 0-9 otherwise)

benford.benford.main()

benford.predictions module

Benford’s predictions for the relative frequencies of numbers.

Successive digit positions are considered individually, starting with the significand and proceeding from left to right towards the least significant digit position.
