Diagnostic Accuracy of Five Serologic Tests for Strongyloides stercoralis Infection [PDF]
, 2014 Background:The diagnosis of Strongyloides stercoralis (S. stercoralis) infection is hampered by the suboptimal sensitivity of fecal-based tests. Serological methods are believed to be more sensitive, although assessing their accuracy is difficult because

Testing for equivalence of diagnostic tests. [PDF]
American Journal of Roentgenology, 1997 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]
Journal of Econometrics, 2008 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]
Medical Mycology, 2005 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.
