Ncrossval

Purpose

Cross-validation for multilinear PLS (NPLS).

Synopsis

[press,cumpress,rmsecv,rmsec,cvpred,misclassed] = ncrossval(x,y,rm,cvi,ncomp,out,pre)

Description

Performs cross-validation of NPLS. If two-way unfold-PLS is desired convert input x to two-way x. By default, the data are centered across the first mode, but no scaling is applied. This can be changed by using additional input arguments. INPUTS:

• x = X-block matrix,
• y = Y-block matrix, and
• rm = regression method (must be 'npl')
• cvi = see CROSSVAL
• ncomp = maximum number of factors.
• out = see CROSSVAL
• pre = see CROSSVAL

OUTPUT:

• See CROSSVAL
