Identifying "gold standard" diagnostic tests can promote evidence-based neonatology practice. Hemolysis is a pathological shortening of the erythrocyte lifespan, differing from erythrocyte senescence in responsible mechanisms and clinical implications. Diagnosing hemolysis goes beyond a binary (yes vs. no) determination.

Two phenomena emerge: 1) When diagnostic test errors are statistically independent from inaccurate ("fuzzy") gold standard (FGS) errors, estimated ...

Commercially Developed Tests of Reading Comprehension: Gold Standard or Fool’s Gold?

Reading Research Quarterly, 2021
ABSTRACTMany seem to believe that researcher‐made tests are unnecessary, if not inappropriate, for evaluating reading comprehension interventions. We suggest that this view reflects a zeitgeist in which researcher‐made (proximal) tests that align with the researchers’ interventions are closely scrutinized and often devalued, whereas commercially ...
