%description
Create, visualize, and test fast-and-frugal decision trees (FFTs) using
the algorithms and methods described by Phillips, Neth, Woike & Gaissmaier
(2017), <doi:10.1017/S1930297500006239>. FFTs are simple and transparent
decision trees for solving binary classification problems. FFTs can be
preferable to more complex algorithms because they require very little
information, are easy to understand and communicate, and are robust
against overfitting.
