Abstract:

In a population of events that are normally expected to occur according to the Poisson distribution, certain events may occur as the results of special factors which operate in relation to them only. In such cases, these specially influenced events will not fall within the Poisson distribution that describes the rest of the population. It may be desirable to study the factors causing their peculiar occurrence, and this will require that the abnormally occurring events be separated from the normally occurring ones. This paper outlines a practical machine method for making this kind of separation for any data that is Poisson distributed. For clarity, the techniques will be described in terms of a particular example, the in-flight failure of vacuum tubes in a piece of airborne electronic equipment. Author
