A comparative analysis of pre-equating and post-equating in a large-scale assessment, high stakes examination [PDF]
Perspectives in Education, 2016 Statistical procedure used in adjusting test score difficulties on test forms is known as “equating”. Equating makes it possible for various test forms to be used interchangeably. In terms of where the equating method fits in the assessment cycle, there

equateIRT: An R Package for IRT Test Equating [PDF]
Journal of Statistical Software, 2015 The R package equateIRT implements item response theory (IRT) methods for equating different forms composed of dichotomous items. In particular, the IRT models included are the three-parameter logistic model, the two-parameter logistic model, the one ...

Comparison of Kernel Equating and Kernel Local Equating in Item Response Theory Observed Score Equating [PDF]
, 2021 The present study aims to compare the Kernel equating and Kernel local equating methods in observed score equating. Functions and error estimates regarding the difference between raw and equated scores and the scores equated by Stocking-Lord and Haebara ...

Bethe equations `on the wrong side of the equator' [PDF]
Journal of Physics A: Mathematical and General, 1999 We analyse the famous Baxter's $T-Q$ equations for $XXX$ ($XXZ$) spin chain and show that apart from its usual polynomial (trigonometric) solution, which provides the solution of Bethe-Ansatz equations, there exists also the second solution which should corresponds to Bethe-Ansatz beyond $N/2$.

Transcendental equation for the Schrödinger equation [PDF]
Mathematics of Computation, 1960 side of eq. (4). The hypergeometric function appearing in eq. (4) can be computed as described above but convergence is slow for values of x close to unity, and in this case it may be desirable to compute the functions differently [4]. A subroutine [5] has been written for the IBM 704 to calculate the toroidal harmonics using the methods described here.

ON A FUNCTIONAL EQUATION [PDF]
The Quarterly Journal of Mathematics, 1958 We have recently discussed in (1) the general solution of a certain functional equation arising in statistical thermodynamics, and we propose in this note to deal with another functional equation arising from the same source(2). The problem is to obtain the most general function f(x) which, for all positive integral values of m, n ...

Automated Essay Scoring Effect on Test Equating Errors in Mixed-format Test
International Journal of Assessment Tools in Education, 2021 Scoring constructed-response items can be highly difficult, time-consuming, and costly in practice. Improvements in computer technology have enabled automated scoring of constructed-response items. However, the application of automated scoring without an

The SQG Equation as a Geodesic Equation [PDF]
Archive for Rational Mechanics and Analysis, 2016 We demonstrate that the surface quasi-geostrophic (SQG) equation given by $$θ_t + \left= 0,\;\;\; θ= \nabla \times (-Δ)^{-1/2} u,$$ is the geodesic equation on the group of volume-preserving diffeomorphisms of a Riemannian manifold $M$ in the right-invariant $\dot{H}^{-1/2}$ metric.
