Good Day All,
I am working with a diagnostic test and comparing the new test to an old
test. Normally I would be able to calculate sensitivity and specificity
quite easily.
However, the 'gold standard' that I am comparing my new diagnostic with is
really 'gold-plated' in that sometimes the 'gold standard' fails completely
and I have no data from the 'gold standard' but I might have data from the
diagnostic test. Of course sometimes my new diagnostic fails but I have
data from my 'gold standard'
To me this really starts moving towards classification but I cannot seem to
find the appropriate calculations.
Can someone point me to some web resources to determine the appropriate
method to be able to deal with the NULLs ? Resources within the medical
realm would be better (because the rest of the folks would understand them
better) but not required.
