WebThe synthesis of hierarchical modeling with item response theory (IRT) has led to psychometric models for item response datasets that possess hierarchical structure. In this entry, an overview is provided of hierarchical IRT methodology and its usefulness as a general framework both for traditional IRT models and new extensions. WebFor the response y and observation number i we have: yi jb,u,b d ˘N(Xib+ Ziu,exp(X d,ib d)) u ˘MVN 0,Is2 u where b are the fixed effects in the mean part of the model, the random effect u represents random vari-ation among clusters of observations and b d is the fixed effect in the residual variance part of the model.

WebHierarchical Multinomial Models. The outcome of a response variable might sometimes be one of a restricted set of possible values. If there are only two possible outcomes, such as male and female for gender, these responses are called binary responses. If there are multiple outcomes, then they are called polytomous responses.
