Statistical Aspects of a New Latent Trait Model
Abstract
dc:descriptionCurrent achievement and aptitude test modeling--item response theory--is based on the overly-optimistic assumption of local independence: that examinee's responses to different test questions will be independent conditional on the latent trait (ability) being measured by the questions. A more realistic account is presented here based on Stout's (1988a, 1988b) notion of essential independence in which the average covariance between the examinee's responses is small but not zero.
