WebJan 9, 2015 · One of the key differences between Classical Test Theory (CTT) and Item Response Theory (IRT) is the way it treats the variance of the latent ability ( θ ). CTT treats the standard error of measurement (SEM) as fixed across the sample: S E M = σ ( 1 − r e l i a b i l i t y) where σ is the standard deviation of the observed scores. WebObjective: This study introduces a new method to establish clinical thresholds for multi-item tests, based on item response theory (IRT), as an alternative to receiver operating characteristic (ROC)

Results: Using either 30% or 100% RH during imbibition of pea seeds, we showed that "live" and "dead" seeds produced clearly discernible "thermal fingerprints", which significantly differed by > 0. ... WebItem response theory based methods are used to compute linking constants and conduct chain linking of unidimensional or multidimensional tests for multiple groups under a common item design.
