An Approximation for the Bias Function of the Maximum Likelihood Estimate of a Latent Variable for the General Case Where the Item Responses Are Discrete.

Samejima, Fumiko

Psychometrika, v58 n1 p119-38 Mar 1993

An approximation for the bias function of the maximum likelihood estimate of the latent trait or ability is developed for the general case where item responses are discrete, which includes the dichotomous response level, the graded response level, and the nominal response level. (SLD)
