LatentREGpp (version 0.2.2)

Item Response Theory Implemented in R and Cpp

Description

Provides a C++ implementation of the Multidimensional Item Response Theory (MIRT) capable of performing parameter and traits estimations. It also provides a list of options to perform an optimal analysis and obtain useful information about the resulting model. This package is a work of SICS Research Group, Universidad Nacional de Colombia.
