under-represented in number. With that dire warning firmly en-

Computing Confidence
In Chapter
12,
Probabilistic Neural Networks, we saw how probability
distributions could be estimated from samples by means of Parzen
windows. We will use that technique later in this chapter. For now,
though, a much more straightforward method is preferable in that it
does not require arbitrary choice of a smoothing parameter or a
particular window function. Also, note that for computing confidence
measures as described above, we do not reall ...
