Another quick query from a medical physicist
(as ever, replies to me not the list please):
I am familiar with traditional diagnostic indices
(e.g. sensitivity and specificity) for quantifying
the efficacy of a particular test when the diagnosis
is based around TWO categories/groups (e.g. benign
versus malignant tumours).
My question is, are there any similar, established
methods/indices for quantifying diagnostic efficacy
when there are MULTIPLE categories/groups (e.g.
malignant tumours, totally benign tumours and
benign tumours regarded clinically as having an
increased chance of progressing into malignant disease
because of co-existant pathology)?
Many thanks in advance, Dave M.
