View source: R/get.hnx.B.initialW.R

Description

To perform ODC method and use some transformation to get the initial input for SODC.

Usage

1
get.hnx.B.initialW(data, k, lambda2)

Arguments

data

A numberic dataset matrix.

k

An integer scalar with the desired number of groups.

lambda2

L2 penalty parameter, if lambda2=-1, then odc.clust choose the optimal lambda2 automatically given lambda2.idx. Otherwise perfoms ODC clustering using given lambda2.

Value

y.initial

The vector derived from the predicted sample scoring matrix Y by ODC.

w.initial

The vector derived from the predicted W by ODC.

what

The predicted W by ODC.

yhat

The predicted sample scoring matrix Y by ODC.

B

A block diagonal matrix with the diagonal component as the normalized Hnx.

hnx

The product of a n by n centering matrix and the input data matrix.
