This package enables three types of subscoring\nmethods within the framework of CTT and IRT, including (1)\nWainer's augmentation method (Wainer et. al., 2001)\n, (2) Haberman's subscoring methods\n(Haberman, 2008) , and (3) Yen's\nobjective performance index (OPI; Yen, 1987)\n.\nIt also includes functions to compute Proportional Reduction of\nMean Squared Errors (PRMSEs) in Haberman's methods which are\nused to examine whether test subscores are of added value. In\naddition, the package includes a function to assess the local\nindependence assumption of IRT with Yen's Q3 statistic (Yen,\n1984 ; Yen, 1993\n).", "NeedsCompilation": "no", "LazyData": "true",
