Linking Parameter Estimates Derived From an Item Response Model Through Separate Calibrations

نویسنده

  • Shelby J. Haberman
چکیده

A regression procedure is developed to link simultaneously a very large number of item response theory (IRT) parameter estimates obtained from a large number of test forms, where each form has been separately calibrated and where forms can be linked on a pairwise basis by means of common items. An application is made to forms in which a two-parameter logistic model is applied to dichotomous items and a general partial credit model is applied to polytomous items.

Linking Item Response Model Parameters

With a few exceptions, the problem of linking item response model parameters from different item calibrations has been conceptualized as an instance of the problem of test equating scores on different test forms. This paper argues, however, that the use of item response models does not require any test score equating. Instead, it involves the necessity of parameter linking due to a fundamental ...

Linking Item Parameters to a Base Scale

This paper compares three methods of item calibration—concurrent calibration, separate calibration with linking, and fixed item parameter calibration—that are frequently used for linking item parameters to a base scale. Concurrent and separate calibrations were implemented using BILOG-MG. The Stocking and Lord (1983) characteristic curve method of parameter linking was used in conjunction with ...

Investigating the Impact of Response Format on the Performance of Grammar Tests: Selected and Constructed

When constructing a test, an initial decision is choosing an appropriate item response format which can be classified as selected or constructed. In large-scale tests where time and finance are of concern, the use of response chosen known as multiple-choice items is quite widespread. This study aimed at investigating the impact of response format on the performance of structure tests. Concurren...

Comparison of Estimates Using Record Statistics from Lomax Model: Bayesian and Non Bayesian Approaches

This paper address the problem of Bayesian estimation of the parameters, reliability and hazard function in the context of record statistics values from the two-parameter Lomax distribution. The ML and the Bayes estimates based on records are derived for the two unknown parameters and the survival time parameters, reliability and hazard functions. The Bayes estimates are obtained based on conju...

plink: An R Package for Linking Mixed-Format Tests Using IRT-Based Methods

This introduction to the R package plink is a (slightly) modified version of Weeks (2010), published in the Journal of Statistical Software. The R package plink has been developed to facilitate the linking of mixed-format tests for multiple groups under a common item design using unidimensional and multidimensional IRT-based methods. This paper presents the capabilities of the package in the co...
