Detecting Differential Item Functioning in 2PL Multistage Assessments
Psych, 2023 The detection of differential item functioning is crucial for the psychometric evaluation of multistage tests. This paper discusses five approaches presented in the literature: logistic regression, SIBTEST, analytical score-based tests, bootstrap score ...

Multidimensionality and Item Bias in Item Response Theory [PDF]
Applied Psychological Measurement, 1992 This paper demonstrates empirically how item bias indexes based on item response theory (IRT) identify bias that results from multidimensionality. When a test is multidimensional (MD) with a primary trait and a nuisance trait that affects a small portion of the test, item bias is defined as a mean difference on the nuisance trait between two groups ...

Advances in item response theory and applications: an introduction [PDF]
, 1982 Test theories can be divided roughly into two categories. The first is classical test theory, which dates back to Spearman’s conception of the observed test score as a composite of true and error components, and which was introduced to psychologists at ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Advances in psychometrics: from Classical Test Theory to Item Response Theory [PDF]
, 2013 In the 20th century, development and evaluation of psychometric properties of tests was mainly based on the Classical Test Theory (CTT). Many tests are long and redundant, with measures influenced by the characteristics of the sample of the individuals ...

Estimating learners' vocabulary size under item response theory
Vocabulary Learning and Instruction, 2014 Perhaps the most qualitatively interpretable vocabulary test score is an estimate of the total number of words the learner knows in the tested domain, such as a frequency word list, or vocabulary taught as part of a course curriculum.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Item response theory analysis of the mechanics baseline test [PDF]
, 2011 Item response theory is useful in both the development and evaluation of assessments and in computing standardized measures of student performance. In item response theory, individual parameters (difficulty, discrimination) for each item or question are ...

Polytomous Item Explanatory Item Response Theory Models [PDF]
Educational and Psychological Measurement, 2019 This study investigates polytomous item explanatory item response theory models under the multivariate generalized linear mixed modeling framework, using the linear logistic test model approach. Building on the original ideas of the many-facet Rasch model and the linear partial credit model, a polytomous Rasch model is extended to the item location ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum
Population Ecology, EarlyView.This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
