| Summary : IRT Separate Calibration Linking Methods
|
Description :
Item 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.
The unidimensional methods include the Mean/Mean, Mean/Sigma, Haebara,
and Stocking-Lord methods for dichotomous (1PL, 2PL and 3PL) and/or
polytomous (graded response, partial credit/generalized partial credit,
nominal, and multiple-choice model) items. The multidimensional
methods include the least squares method and extensions of the Haebara
and Stocking-Lord method using single or multiple dilation parameters
for multidimensional extensions of all the unidimensional dichotomous
and polytomous item response models. The package also includes
functions for importing item and/or ability parameters from common IRT
software, conducting IRT true score and observed score equating, and
plotting item response curves/surfaces, vector plots, information
plots, and comparison plots for examining parameter drift.
