The data are readings on 200 Swiss bank notes, 100 of which are genuine and 100 forged. However, the structure of the samples may not be quite that simple. The forged notes have all been detected and withdrawn from circulation. To provide a useful comparison, the genuine notes are likewise used. So some of the notes in either group may have been misclassified. A second complication is that there may be more than one forger at work.
