Unfortunately, decreasing the number of items is accompanied by a certain degree of bias when the true proficiency level differs significantly from the a priori estimate. The authors suggest that it is possible to reduced the bias, and even the standard error of the estimate, by applying to each provisional estimation one or a combination of the following strategies: adaptive correction for bias proposed by Bock and Mislevy (1982), adaptive a priori estimate, and adaptive integration interval.10a*Bias (Epidemiology)10a*Computers10aData Interpretation, Statistical10aModels, Statistical1 aRaiche, G1 aBlais, J G uhttp://www.iacat.org/content/considerations-about-expected-posteriori-estimation-adaptive-testing-adaptive-priori
