IDEAScripts

Zap ConsultingData analytics can test 100% of data to detect suspicious transactions for further investigation. Data analytics can also be used to examine, collate, and quantify transactions once an audit target area have been identified. GEL-1 is an example of an IDEAScript available on this website that can help to determine an audit target. Whistle-blowing and tips hotlines also provides high value areas to review and investigate. It is important for all organizations to have open communications and transparency with information that can be gathered to help narrow the search for the data analytical analyst.  One such service is Integrity Hotline™ (http://zapconsulting.ca/en-GB/integrityhotline) where they strive to provide organizations and their communities with a professional, anonymous, transparent, reporting mechanism to aid in the integrity of their business operations, detour financial frauds, while encouraging the organization’s community confidence and minimizing toxicity in the business environment. Integrity Hotline™ assists organizations in achieving positive corporate governance, with fairness, transparency and professionalism.

Benford's law 1st digit test

Background: 

This will perform the Benford 1st digit test on each distinct item in a selected column.  So if you have a vendor column this would perform the test for each vendor.  It allows you to exclude low value items.

September 2015 - The interface has been rewritten along with some updates. 

Benford's law 1st 2 digit test

Background: 

This will perform the Benford 1st 2 digit test on each distinct item in a selected column.  So if you have a vendor column this would perform the test for each vendor.  It allows you to exclude low value items.

Updated for IDEA v9 on Feb 14, 2013.

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.

Relative Size Factor Test (RSF) - Updated Oct 24, 2012

Background: 

The purpose of the Relative Size Factor test (RSF) IDEAScript is to identify anomalies where the largest amount for subsets in a given key is outside the norm for those subsets. This test compares the top two amounts for each subset and calculates the RSF for each. The RSF test is based on Chapter 11 of Mark J. Nigrini’s book, entitled, “Forensic Analytics: Methods and Techniques for Forensic Accounting Investigations”.

Compare multiple fields

Background: 

This script will take the same file from different points and time and compare multiple fields. Currently the compare funciton in IDEA only allows to compare on one field based on an amount field. This will allow for comparison of text and date fields also.

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.
