Sentence examples for model of item from inspiring English sources

The original 4-factor model of item responses is informative for identifying meaningful clusters of depressive symptoms in dementia caregivers [ 55, 56].

Theoretical and empirical comparison of Mokken and Rasch models of item response theory [ 12] show that in situations where all this is required is the ordering of people on a latent trait that Mokken scaling, being less restrictive than Rasch modelling, is sufficient and guarantees ordinal measurement of persons on the latent trait, provided the model applies.
Results also showed that the Stoma-QOL conforms to the Rasch model expectation of item weight invariance between national versions in different European countries.
