I have identified potential fraud in a limited number of employees' time keeping postings and would like to figure out how to test if it is prevalent throughout the company.
Here's the scenario: Looking at daily time sheet records I identified that certain employees had identical daily time sheets for an entire year (total hours each consecutive day were equal for every day of the year). While I only identified a few sets of employees with identical records for an entire year, I want to test whether it was occurring for smaller time periods (like one or two months at a time).
There are about 100 employees I want to test against one another over a 2-3 year period. Anyone have an idea how to do this?
