An approximate statistical test of the equality of two
intraclass reliability coefficients based on the same
sample of people is derived. Such a test is needed when a
researcher wishes to compare the reliability of two ...
A new item-fit index is proposed that is both a
descriptive measure of deviance of single items and an
index for statistical inference. This index is based on
the assumptions of the dichotomous and polytomous
The selection of items from a calibrated item bank for
fixed-form tests is an optimal test design problem; this
problem has been handled in the literature by mathematical
programming models. A similar problem, ...
Factor analysis of data that conform to the unfolding
model often results in an extra factor. This artificial
extra factor is particularly important when data that
conform to a bipolar unidimensional unfolding scale

Appropriateness measurement in nonparametric item
response theory modeling is affected by the reliability of
the items, the test length, the type of aberrant response
behavior, and the percentage of aberrant persons in ...
