Effects of Differential Item Discriminations between Individual - Level and Cluster - Level under the Multilevel
Item Response Theory Model
It is
an item response theory model which helps to make a linear interval scale, to fit the model.
It is
an item response theory model which helps to describe the required scaling properties of linear interval measurement and the response pattern observed in the data corresponds to the theoretical pattern expected by the model (Embretson & Reise, 2000; Tennant & Conaghan, 2007).
