Diagnostic Value

[AlanB]

What is the meaning of the diagnostic value numbers and how they are calculated? I understand that the higher values mean greater diagnostic value, but does a specific value, for example 0.50, be interpreted as capable of reducing uncertainty by some specific amount?

Thanks,
Alan

This is number is, roughly speaking, the expected gain in cross-entropy between the pursued fault and the test in question. I'm afraid I cannot assign much absolute meaning to that . 0.5 strikes me as high but "that's all I had to say about that" (quoting Forrest Gump ).
Hope this helps,
