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

Outputs
