Item-Weighted Likelihood Method for Ability Estimation in Tests Composed of Both Dichotomous and Polytomous Items

Tao, Jian; Shi, Ning-Zhong; Chang, Hua-Hua - In: Journal of Educational and Behavioral Statistics 37 (2012) 2, pp. 298-315

For mixed-type tests composed of both dichotomous and polytomous items, polytomous items often yield more information than dichotomous ones. To reflect the difference between the two types of items, polytomous items are usually pre-assigned with larger weights. We propose an item-weighted...
