'Some fraud of course, will be unintentional and we will consider each case based on its own merits'
This statement from Warwick's web site is ridiculous. Unintentional fraud.
It looks very likely that the contents of Warwick's web page is a garbled version of some of the NFI related nonsense about discounts. For the NFI is fond of saying that there should be no assumption as to whether a MATCH arises from fraud or error until there has been an investigation, neatly, but falsely implying that only one of these two explanations is possible. There is of course a third explanation, that the 'match' in question is an example of NFI data mining ie the use of computing to produce lists of cases where there 'might' on statistical or a priori grounds be an inconsistency.
It will be interesting to see whether Blogging Warwick's mistakes leads them to change this nonsense.
