The appropriateness of a traditional correlational
measure of halo error (the difference
between dimensional rating intercorrelations and
dimensional true score intercorrelations) is
reexamined in the context of three ...
The advantages of the Kalman filter as a factor
score estimator in the presence of longitudinal data
are described. Because the Kalman filter presupposes
the availability of a dynamic state space
model, the state space ...
A procedure is presented to generate standardized
scores from raw test data that are, as far as
possible, age independent and normally distributed.
The model is fitted to the percentile points of
the raw score distribution, ...
A theoretical framework for mastery testing
based on item response theory and Bayesian decision
theory is described. The idea of sequential
testing is developed, with the goal of providing
shorter tests for individuals ...
Real and simulated datasets were used to
investigate the effects of the systematic variation of
two major variables on the operating characteristics
of computerized adaptive testing (CAT)
applied to instruments consisting ...
