Multidimensional Adaptive Testing with a Minimum Error-Variance Criterion.
van der Linden, Wim J.
Journal of Educational and Behavioral Statistics, v24 n4 p398-412 Win 1999
Proposes an algorithm that minimizes the asymptotic variance of the maximum-likelihood (ML) estimator of a linear combination of abilities of interest. The criterion results in a closed-form expression that is easy to evaluate. Also shows how the algorithm can be modified if the interest is in a test with a "simple ability structure." (SLD)
