CAT-class

An S4 class for computerized adaptive tests

Provides functions to more easily analyze computerized adaptive tests. Currently, functions for computerized
adaptive tests (CAT), computer adaptive multistage tests (CMT), and mixed computer adaptive multistage tests (McaMST)
utilizing CAT item-level adaptation for the initial stage and traditional MST module-level adaptation for the subsequent
stages have been created, and a variation of Hybrid computer adaptive MST is planned as well. For an in-depth look at
CAT and MST, see Weiss & Kingsbury (1984) <doi:10.1111/j.1745-3984.1984.tb01040.x> and Luecht & Nungester
(2000) <doi:10.1007/0-306-47531-6_6> respectively.
