Modalclust (version 0.7)

hmac: Perform Modal Clustering in serial mode only

Description

Performs Modal Cluster with specified smoothing paramters. Used as a sub function of phmac.

Usage

hmac(dat,Sigmas,G=NULL,member=NULL)

Arguments

dat

Matrix of data points

Sigmas

Specified smoothing levels

G

Specified values of modes. A matrix with number of rows equal to the number of modes and number of columns equal to the dimension of the data. Defualt value is NULL

member

Membership of the observations to the modes given in G. Default value is NULL

Value

data

Same as the input dat.

n.cluster

Number of clusters at each level.

level

Levels corresponding to each smoothing parameter.

Sigmas

Same as input sigmas.

mode

List of modes at each distinct levels.

membership

List of memmbership to modes at each distinct levels.
