IRT Model with Personal Guessing Levels


Христов, Любомир (2005) IRT Model with Personal Guessing Levels Internaional Conference on Computer Systems and Technlologies – CompSysTech'2005, Varna


 In this paper we offer a modification of the 3-parametric logistic model by introducing of personal guessing level parameters which appears to be interesting and useful in some specific test situations. We offer a computer implementation of the model on the basis of the well-known MMLE/EM parameter estimation technique. Also here we use the BFGS quasi-Newton method instead of the traditional Newton-Raphson method in solving of the maximum likelihood equations.
