%description
Nonparametric smoothing methods for density and regression estimation and
inference with circular data. The package provides kernel density
estimation along with inferential tools such as circular SiZer for feature
significance, mode estimation, and modal clustering. It includes multiple
methods for selecting the smoothing parameter, allowing users to optimize
the trade-off between bias and variance. Various plotting functions help
visualize estimated densities, modes, clusters, and significance features.
For regression, the package implements nonparametric estimation of the
mean regression function as well as other conditional characteristics,
including modal regression and generalized regression. Bandwidth selection
is also supported in the regression context, and testing procedures are
available to assess structural features or effects in circular regression
models.
