Title: Empirical priors in computerized adaptive testing: risk and reward
Abstract: Computerized adaptive testing (CAT) is a powerful tool in test development that can be used to administer tests that are tailor made to the participant. Available information about the participant can be used to make a CAT more efficient and precise, but not without risk. During this productive lunch break I will try to explain the benefits and risks of using empirical priors in CATs with dichotomous items. In addition, we will look at some simulation results to see how these risks generalize to CATs with polytomous items.
