SIMULATED EQUATING USING SEVERAL ITEM RESPONSE CURVES

Selection the best Method of Equating Using Anchor-Test Design‎ in Item Response Theory ‎‎

Explaining the problem. The equating process is used to compare the scores of the two different tests with the same theme‎. ‎The goal of this research is finding the best method of equating data using Logistic model. ‎ Method. we are using the data of Ph.D‎. ‎test in Statistic major for two consecutive years 92 and 93‎. ‎For analyzing‎, ‎we are specifically using the tests of Statistics major ...

Bayesian Estimation of Item Response Curves

We will consider dichotomous responses to a set of test items which are designed to measure the abilities of individuals. We assume that each item is characterized by an item response curve, a function of ability which is indexed by unknown parameters called item parameters. We consider a Bayesian method for estimating these parameters when the abilities of the individuals are assumed to have a...
