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
dataSame as the input dat.
n.clusterNumber of clusters at each level.
levelLevels corresponding to each smoothing parameter.
SigmasSame as input sigmas.
modeList of modes at each distinct levels.
membershipList of memmbership to modes at each distinct levels.
