%description
Computes Logistic Knowledge Tracing ('LKT') which is a general method for
tracking human learning in an educational software system. Please see
Pavlik, Eglington, and Harrel-Williams (2021)
<https://ieeexplore.ieee.org/document/9616435>. 'LKT' is a method to
compute features of student data that are used as predictors of subsequent
performance. 'LKT' allows great flexibility in the choice of predictive
components and features computed for these predictive components. The
system is built on top of 'LiblineaR', which enables extremely fast
solutions compared to base glm() in R.
