چکیده

The R package kequate enables observed-score equating using the kernel method of test equating. We present the recent developments of kequate, which provide additional support for item-response theory observed score equating using 2-PL and 3-PL models in the equivalent groups design and non-equivalent groups with anchor test design using chain equating. The implementation also allows for local equating using IRT observedscore equating. Support is provided for the R package ltm.

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...

Statistical Equating Methods

The R package equate (Albano, 2010) contains functions for non-IRT equating under random groups and nonequivalent groups designs. This package vignette introduces these designs and provides an overview of statistical equating with details about each of the supported equating methods. Examples demonstrate the basic functionality of the package.

A comparison of Van der Linden's conditional equipercentile equating method with other equating methods under the random groups design

To ensure test security and fairness, alternative forms of the same test are administered in practice. However, alternative forms of the same test generally do not have the same test difficulty level, even though alternative test forms are designed to be as parallel as possible. Equating adjusts for differences in difficulties among forms of the test. Six traditional equating methods are consid...

Standard Error Estimation of 3PL IRT True Score Equating With an MCMCMethod

A Markov chain Monte Carlo (MCMC) method and a bootstrap method were compared in the estimation of standard errors of item response theory (IRT) true score equating. Three test form relationships were examined: parallel, tauequivalent, and congeneric. Data were simulated based on Reading Comprehension and Vocabulary tests of the Iowa Tests of Basic Skills1. For parallel and congeneric test form...
