feature
feature-package.RdPackage for feature significance for multivariate kernel density estimation.
Details
The feature package contains functions to display and compute kernel density estimates, significant gradient and significant curvature regions. Significant gradient and/or curvature regions often correspond to significant features (e.g. local modes).
There are two main functions in this package.
featureSignifGUI is the interactive function where
the user can select bandwidths from a pre-defined range. This
mode is useful for initial exploratory
data analysis. featureSignif is the non-interactive function.
This is useful when the user has a more
definite idea of suitable values for the bandwidths. The latter is closely related
to the ks::kfs function.
For a more detailed example for 1-, 2- and 3-d data, see
vignette("feature").
