modecent: Returns locations of modes of a density estimate

In denpro: Visualization of Multivariate Functions, Sets, and Data

Description

With "modecent" we may find the location of the modes of a function. Argument to function "modecent" is the level set tree of the function. A mode is defined here to be the barycenter of a set at which the estimate has a local maximum.

Usage

modecent(lst)

Arguments

lst	level set tree object; list containing lst$parent and lst$center; output of "leafsfirst", "profgene", "profhist", or "profkern"

Value

modenum*d-matrix; for each mode its location. The rows of output are d-vectors specifying the locations of the modes.
