%description
Fitting, cross-validating, and predicting with Bayesian Knowledge Tracing
(BKT) models. It is designed for analyzing educational datasets to trace
student knowledge over time. The package includes functions for fitting
BKT models, evaluating their performance using various metrics, and making
predictions on new data. It provides the similar functionality as the
Python package pyBKT authored by Zachary A. Pardos (zp@berkeley.edu) at
<https://github.com/CAHLR/pyBKT>.
