Implementation of the EM Algorithm in the Estimation of Item Parameters : The BILOG Computer Program / Robert J. Mislevy and R. Darrell Bock.

This paper reviews the basic elements of the EM approach to estimating item parameters and illustrates its use with one simulated and one real data set. In order to illustrate the use of the BILOG computer program, runs for 1-, 2-, and 3-parameter models are presented for the two sets of data. First...
