%description
Implementation of Energy Trees, a statistical model to perform
classification and regression with structured and mixed-type data. The
model has a similar structure to Conditional Trees, but brings in Energy
Statistics to test independence between variables that are possibly
structured and of different nature. Currently, the package covers
functions and graphs as structured covariates. It builds upon 'partykit'
to provide functionalities for fitting, printing, plotting, and predicting
with Energy Trees. Energy Trees are described in Giubilei et al. (2022)
<arXiv:2207.04430>.
