Hi, does someone have a solution to get Benford's law analysis done in LAE? (http://en.wikipedia.org/wiki/Benford%27s_law)

This is somewhat standard feature in many data analysis products such as Caseware IDEA and ACL, and in my opinion would be very useful to have in LAE, too.

Thanks!

Hi,
It's relatively simple to implement the Benford's law logic in LAE.
Some time ago I developed a couple of library nodes which perform simple 1 and 2 digit Benford�s law analysis on a set of currency amounts.
A graph and some sample data to drive it are attached.
The graph includes two library nodes:

• 1-Digit Benford � extracts the 1st (left-most) digit of an input field and calculates the % distribution of this across the set of amount values. The Bedford probability is also calculated using the standard log10(1 + 1/n) formula and the deviation of the digit distribution from Benford is output.
• 2-Digit Benford � as above but uses left-most 2 digits of an input field.

Let me know if you have any questions about this.

Regards,
Mario Ermacora
