摘要
该文介绍了一种新的等值方法-核等值法。首先介绍了核等值法的研究过程、它的主要特点以及五个步骤(前平滑处理、估计分数概率、连续化、等值、计算等值标准误)。之后,介绍了核等值法与其他传统的观察分等值方法的差异,最后是对核等值法的评价。
This paper presents a new equating method the kernel method of test equating. First, the historical background of the research is introduced, followed by its main features and its five steps （presmoothing, score probability estimation, eontinuization, equating, and compu- tation of standard error of equating）. Then the differences between the kernel method and other traditional observe score equating methods are stated and the last part presents the evaluation and comments on the kernel method.
