Ecological Validity of Performance Validity Testing [PDF]
Archives of Clinical Neuropsychology, 2014 Performance validity tests (PVTs) have been shown to relate to neuropsychological performance, but no studies have looked at the ecological validity of these measures. Data from 131 veterans with a history of mild traumatic brain injury from a multicenter Veterans Administration consortium were examined to determine the relation between scores on a ...

VALID HETEROSKEDASTICITY ROBUST TESTING
Econometric Theory, 2023 Tests based on heteroskedasticity robust standard errors are an important technique in econometric practice. Choosing the right critical value, however, is not simple at all: conventional critical values based on asymptotics often lead to severe size distortions, and so do existing adjustments including the bootstrap.

Biomarker validation and testing [PDF]
Molecular Oncology, 2014 A tumor biomarker is a molecular or process‐based change that reflects the status of an underlying malignancy. A tumor biomarker may be identified and measured by one or more assays, or tests, for the biomarker. Increasingly, tumor biomarker tests are being used to drive patient management, either by identifying patients who do not require any, or any ...

Testing and Validating the Quality of Specifications [PDF]
2008 IEEE International Conference on Software Testing Verification and Validation Workshop, 2008 Model-based testing of state based systems is known to be able to spot non-conformance issues. However, up to half of these issues appear to be errors in the model rather than in the system under test. Errors in the specification at least hamper the prompt delivery of the software, so it is worth while to invest in the quality of the specification ...

Psychological Bulletin, 1955 Validation of psychological tests has not yet been adequately conceptualized, as the APA Committee on Psychological Tests learned when it undertook (1950-54) to specify what qualities should be investigated before a test is published. In order to make coherent recommendations the Committee found it necessary to distinguish four types of validity ...

Specimen Validity Testing: Is it “Valid” for Drug Testing in Pain Management? [PDF]
The Journal of Applied Laboratory Medicine, 2018 The goal of drug testing in the pain management population is to confirm compliance with prescribed medications and identify aberrant behaviors, such as use of an illicit substance or pharmaceutical drugs not prescribed. Specimen validity testing (SVT)2 is often used to ensure that the provided sample has not been diluted, substituted, or adulterated ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
