Calculate Projection Pursuit index

Description

For given projected data and class information, calculate projeciton pursuit index.

Usage

 PPindex.class(PPmethod,data,class,weight=TRUE,r=NULL,lambda=NULL,...)
 PPindex.LDA(data,class, weight = TRUE, ...) 
 PPindex.Lp(data, class, r, ...) 
 PPindex.PDA(data,class,lambda,...)

Arguments

PPmethod Selected PP index
``LDA" - LDA index
``Lp" - Lp index
``PDA" - Entropy-class index
data A data without class information
class class information
weight weight flag using in LDA index
r a parameter for L^r index
lambda a parameter for PDA index
... ...

Value
