%description
The user has the option to utilize the two-dimensional density estimation
techniques called smoothed density published by Eilers and Goeman (2004)
<doi:10.1093/bioinformatics/btg454>, and pareto density which was
evaluated for univariate data by Thrun, Gehlert and Ultsch, 2020
<doi:10.1371/journal.pone.0238835>. Moreover, it provides visualizations
of the density estimation in the form of two-dimensional scatter plots in
which the points are color-coded based on increasing density. Colors are
defined by the one-dimensional clustering technique called 1D distribution
cluster algorithm (DDCAL) published by Lux and Rinderle-Ma (2023)
<doi:10.1007/s00357-022-09428-6>.
