View Full Version : Numerical frequency analysis query

03-08-2010, 07:52 AM

I heard about this on radio 4 (UK) back in 2007. A statistical method whereby the frequency of integers in a dataset is calculated, then compared to a standard table in order to detect whether the data has been meddled with (Just as with letter frequency analysis in cryptography).

I understand that some businesses use it to assess expenses claims among other things. Has anyone heard of it? I've been unable to find any more information,

Many thanks,
