Purpose

Calculate a single latent variable for partial least squares (PLS) regression.

Synopsis

[p,q,w,t,u] = plsnipal(x,y)

Description

PLSNIPAL is called by the routine pls to calculate each latent variable in a partial least squares regression.

Inputs

  • x = x-block input data (for first PLS latent variable), or x-block residuals (for subsequent latent variables)
  • y = y-block input data (for first PLS latent variable), or y-block residuals (for subsequent latent variables)

Outputs

  • p = x-block latent variable loadings
  • q = y-block latent variable loadings
  • w = x-block latent variable weights
  • t = x-block latent variable scores
  • u = y-block latent variable scores
