Abstract: | In this paper, we develop a new curvilinear equating for the nonequivalent groups with anchor test (NEAT) design under the
assumption of the classical test theory model, that we name curvilinear Levine observed score equating. In fact, by applying
both the kernel equating framework and the mean preserving linear transformation of post-stratification equating, we obtain
a family of observed score equipercentile equating functions, which also includes the classical Levine observed score linear equating and the Tucker linear equating
as special cases. |
