title: 'PPtreeExt: Projection Pursuit Classification Tree Extensions'
version: 0.1.0
doi: 10.32614/CRAN.package.PPtreeExt
abstract: 'Implements extensions to the projection pursuit tree algorithm for supervised
  classification, see Lee, Y. (2013), <https://doi.org/10.1214/13-EJS810> and Lee,
  E-K. (2018) <https://doi.org/10.18637/jss.v083.i08>. The algorithm is changed in
  two ways: improving prediction boundaries by modifying the choice of split points-through
  class subsetting; and increasing flexibility by allowing multiple splits per group.'
