Temporal Dimension in Reference Standard Misclassification – A Concept Note [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2014
In situations of diagnostic tests studies where the gold standard (GS) test is not absolutely perfect, validity measures of index tests vary in subgroups with varying disease prevalence. This is called reference standard misclassification. Although this

Recognizing the Italian zones most prone to next large earthquakes: possible approaches and present chances

open access: yesAnnals of Geophysics, 1997
The defense from earthquakes in Italy would be considerably favoured by knowing where the next strong shocks will most probably occur. However, to obtain this information a well-defined and widely accepted method is not yet available. This work discusses
