Minimum Normalised Cut Hyperplane (inherits from HP class)

This function calls:

binAssign Assigns true cluster label (labels) of each observation to the element of the binary partition (clusters = {1,2}^n) that contains the majority of its observations
hp Class implementing generic hyperplane interface
pcacomp Returns the principal components of (X) specified in vector (index)
success_ratio Quantifies accuracy with which a binary partition splits data containing two or more clusters
fgt_kde Interface to improved Fast Gauss Transform to compute one-dimensional KDE with Gaussian kernels
f_ncut Function value, split point, and cluster assignment for minimum normalised cut projection index
nchp Minimum Normalised Cut Hyperplane (inherits from HP class)
ncut_sigma Default scaling parameter employed by Gaussian kernel in minimum normalised cut projection pursuit
ncutpp Minimum normalised cut projection pursuit
