%description
Implements methods for obtaining kernel density estimates subject to a
variety of shape constraints (unimodality, bimodality, symmetry, tail
monotonicity, bounds, and constraints on the number of inflection points).
Enforcing constraints can eliminate unwanted waves or kinks in the
estimate, which improves its subjective appearance and can also improve
statistical performance. The main function scdensity() is very similar to
the density() function in 'stats', allowing shape-restricted estimates to
be obtained with little effort. The methods implemented in this package
are described in Wolters and Braun (2017)
