Research on Standard Errors of Equating Differences. Research Report. ETS RR-10-25
Moses, Tim; Zhang, Wenmin

In this paper, the "standard error of equating difference" (SEED) is described in terms of originally proposed kernel equating functions (von Davier, Holland, & Thayer, 2004) and extended to incorporate traditional linear and equipercentile functions. These derivations expand on prior developments of SEEDs and standard errors of equating and provide additional insight about the relationships of kernel and traditional equating functions. Simulations are used to evaluate the SEEDs' accuracies. (Contains 3 tables and 12 figures.)
