The Relationship between the Bock-Aitkin Procedure and the EM Algorithm for IRT Model Estimation [electronic resource] / Yaowen Hsu, Terry A. Ackerman and Meichu Fan.

It has previously been shown that the Bock-Aitkin procedure (R. Bock and M. Aitkin, 1981) is an instance of the EM algorithm when trying to find the marginal maximum likelihood estimate for a discrete latent ability variable (latent trait). In this paper, it is shown that the Bock-Aitkin procedure i...
