Part of the Use R! book series (USE R)


In the first part of this book, focus was put on computerized adaptive testing and the R package catR was presented as a tool to simulate CAT patterns and scenarios. In the context of multistage testing, the R package mstR was developed in a similar spirit. This chapter provides a brief description of mstR, with emphasis on main differences between mstR and catR for specific MST purposes.
