Package for feature significance for multivariate kernel density estimation.
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.
For a more detailed example for 1-, 2- and 3-d data, see
vignette("feature").
