This package wraps some R (GPL-2/3) libraries for fitting IRT (Item Response Theory) latent variable models and running CATs (Computer-Adaptive Tests).
The wrapped IRT libraries are:
- mirt (GPL-3)
- kernsmoothirt (GPL-2)
The wrapped CAT libraries are:
Using wrappers typically come with a bunch of drawbacks. The main purpose of these wrappers is for use in demos and for contently comparing results with Julia code, i.e., more notebook and script level code than final applications.
This library is MIT licensed. However, using this library will typically cause
your program to link to R (via RCall.jl), which may cause your program to
become a derivative work under the GPL-2/3. Fetching and making use of the use
of the packages may additionally trigger GPL-3 for mirt or GPL-2 for
kernsmoothirt. Moreover, linking both at the same time may create a license
incompatibility between GPL-2 and GPL-3! See you in court!
