The Role of Collateral Information about Examinees in Item Parameter Estimation.
Mislevy, Robert J.; Sheehan, Kathleen M.
Psychometrika, v54 n4 p661-79 Dec 1989
Standard procedures for estimating item parameters in item response theory ignore collateral information that may be available about examinees. Circumstances under which collateral information about examinees may be used to make inferences about item parameters more precise and circumstances under which collateral information must be used are described.
