  • The dataset data.fraction2 is the fraction subtraction data set with 536 students and 11 items. For this data set, several \(Q\) matrices are available. The data is a list. The first entry data contains the data frame. The entry q.matrix1 contains the Q-matrix of Henson, Templin and Willse (2009). The third entry q.matrix2 is an alternative Q-matrix of de la Torre (2009). The fourth entry is a modified Q-matrix of q.matrix1.
