Performing the Kernel Method of Test Equating with the Package kequate

open access: yesJournal of Statistical Software, 2013
In standardized testing it is important to equate tests in order to ensure that the test takers, regardless of the test version given, obtain a fair test.

Local Observed‐Score Kernel Equating

open access: yesJournal of Educational Measurement, 2014
Three local observed‐score kernel equating methods that integrate methods from the local equating and kernel equating frameworks are proposed. The new methods were compared with their earlier counterparts with respect to such measures as bias—as defined by Lord's criterion of equity—and percent relative error.

A Review of Test Equating Methods with a Special Focus on IRT-Based Approaches

open access: yesStatistica, 2018
The overall aim of this work is to review test equating methods with a particularly detailed description of item response theory (IRT) equating. Test score equating is used to compare different test scores from different test forms.

Evaluating Equating Transformations in IRT Observed-Score and Kernel Equating Methods. [PDF]

open access: yesAppl Psychol Meas, 2023
Test equating is a statistical procedure to ensure that scores from different test forms can be used interchangeably. There are several methodologies available to perform equating, some of which are based on the Classical Test Theory (CTT) framework and ...

Standard Errors of Kernel Equating: Accounting for Bandwidth Estimation. [PDF]

open access: yesAppl Psychol Meas, 2022
In standardized testing, equating is used to ensure comparability of test scores across multiple test administrations. One equipercentile observed-score equating method is kernel equating, where an essential step is to obtain continuous approximations to

Contributions to Kernel Equating

open access: yes, 2014
The statistical practice of equating is needed when scores on different versions of the same standardized test are to be compared. This thesis constitutes four contributions to the observed-score equating framework kernel equating. Paper I introduces the open source R package kequate which enables the equating of observed scores using the kernel method

Kernel Equating Under the Non-Equivalent Groups With Covariates Design. [PDF]

open access: yesAppl Psychol Meas, 2015
When equating two tests, the traditional approach is to use common test takers and/or common items. Here, the idea is to use variables correlated with the test scores (e.g., school grades and other test scores) as a substitute for common items in a non ...

Degenerate Kernel Method for Hammerstein Equations [PDF]

open access: yesMathematics of Computation, 1991
The classical method of the degenerate kernel method is applied to numerically solve the Hammerstein equations. Several numerical examples are given to demonstrate the effectiveness of the current method. A brief discussion of a number of methods to decompose the kernel is also included.

On an Integral Equation with the Riemann Function Kernel

open access: yesAxioms, 2022
This paper is concerned with a study of a special integral equation. This integral equation arises in many applied problems, including transmutation theory, inverse scattering problems, the solution of singular Sturm–Liouville and Shrödinger equations, and the representation of solutions of singular Sturm–Liouville and Shrödinger equations.
