ITERATIVE ЕAP PARAMETER ESTIMATION FOR SOME BINARY MODELS FROM THE ITEM RESPONSE THEORY


Христов, Любомир (2011) ITERATIVE ЕAP PARAMETER ESTIMATION FOR SOME BINARY MODELS FROM THE ITEM RESPONSE THEORY NVU Scientific Conference, Veliko Tirnovo 2010


 In the present work we consider a method for parameter estimation of some binary models from the Item Response Theory based on two-stage scheme: (1) estimation of the item parameters and (2) estimation of the abilities. On the successive iterations we take the corresponding expected a posteriori (ЕAP) estimates. The proposed algorithm uses the appropriate a priori distributions and typically is converging to realistic values of parameters.
