Testing for equivalence of diagnostic tests. [PDF]
T he technology of diagnostic radiology is changing rapidly. Associated with these changes is a need to compare technologies with one another in an appropriate and valid fashion. To make meaningful comparisons, appropriate questions must be asked and tested. However, in comparing diagnostic technologies, we ot’ten ask and test the wrong question.

Diagnostic testing for cointegration [PDF]
We develop a sequence of tests for specifying the cointegrating rank of, possibly fractional, multiple time series. Memory parameters of observables are treated as unknown, as are those of possible cointegrating errors. The individual test statistics have standard null asymptotics and are related to Hausman specification test statistics: when the ...

Advances in diagnostic testing [PDF]
Within the past decade surrogate markers have become important and reliable tools for the early diagnosis of invasive aspergillosis. Surrogate markers include the antigens galactomannan and (1 --> 3)-beta-D-glucan for which commercial assays are available, as well as fungal DNA for which experimental PCR assays have been developed.
