The Bias Function of the Maximum Likelihood Estimate of Ability for the Dichotomous Response Level.

Samejima, Fumiko

Psychometrika, v58 n2 p195-209 Jun 1993

F. Samejima's approximation for the bias function for the maximum likelihood estimate of the latent trait in the general case where item responses are discrete is explored. Observations are made about the behavior of this bias function for the dichotomous response level in general. Empirical examples are given. (SLD)
