<p>SIMPLS is much faster than
  the NIPALS algorithm, especially when the number of X variables
  increases, but gives slightly different results in the case of
  multivariate Y. SIMPLS truly maximises the covariance criterion.
  According to de Jong, the standard PLS2 algorithms lie closer to
  ordinary least-squares regression where a precise fit is sought;
  SIMPLS lies closer to PCR with stable  predictions.</p>
