subscore: Computing Subscores in Classical Test Theory and Item Response
Theory
Functions for computing subscores for a test using different
methods in both classical test theory (CTT) and item response theory (IRT). This
package enables three sets of subscoring methods within the framework of CTT
and IRT: Wainer's augmentation method, Haberman's three subscoring methods, and
Yen's objective performance index (OPI). The package also includes the function
to compute Proportional Reduction of Mean Squared Errors (PRMSEs) in Haberman's
methods which are used to examine whether test subscores are of added value.
