Further results on indices for diagnostic screening
B. M. BennettSummary
In continuation of an earlier paper (B
ennett
, 1975) a further examination of the concepts of sensitivity (=
ξ
), specificity (=
η
) and predictive value (=
ϱ
) for a diagnostic test
T
is made. In particular the relation of predictive value
ϱ
to B
ayes
' theorem is examined, as well as various limiting situations for values of
ξ, η
and
ϱ
. While not all the results are novel, this paper presents these in a systematic way.
