Equating with bivariate log-linear presmoothing under the common-item nonequivalent groups design: structural zeros and their implications
In equating, when common items are internal and scoring is in terms of the number of correct items, some pairs of total scores (X) and common-item scores (V ) can never be observed in a bivariate distribution of X and V ; these pairs are called structural zeros (Bishop, Fienberg, & Holland, 2007; Holland & Wang, 1987). This study examines how different approaches to handling structural zeros gi...

The purpose of this study was to evaluate the effectiveness of the hybrid Levine equipercentile (Hybrid LE) and modified frequency estimation (MFE) equating methods in improving accuracy of equating as compared to the percentile rank frequency estimation (FE), kernel frequency estimation (Kernel FE) and percentile rank chained equipercentile (CE) equating methods under the common-item nonequiva...
