Last-Two Digits Test

Background

This script is based on Mark J. Nigrini's Forensic Analytics book -  Chapter 8 - The Last-Two Digits Test.  This test is a powerful test for number invention or number creativity.  The test identifies abnormal duplications on the right side, these duplications could indicate errors, invented numbers, or excessive rounding.  To run this test, select the file you wish to perform the test on and the amount field.  The resulting file will have 100 transactions showing the last two digits i.e. 01 to 99 and the difference with the expected rate

Cross Join - Updated July 2015

Background

The cross join script will take two files that do not have a common key and creates a new file containing all records from both files. - The menu has been updated.

July 2015 - I have rewritten the interface, probably not much of a difference for the user but the backend should work better and the dialog won't close each time you make a selection.  It will also work for time fields.  It currently ignores virtual and boolean fields, they won't be copied over to the new file.

GEL - 1

Background

The GEL tests establish possible links between two selected fields over the entire data set. The first field is the key field and the second field is the element factor.

The test was updated in October 2015.
