  z: pcs
  idx: x(idx) maps to z

  x: data matrix
  shifts: array of shifts to apply
  keep: number of components shifted regressor PCs to keep (default: all)
  threshold: discard PCs with eigenvalues below this (default: 0)
  w: ignore samples with absolute value above this

 mean is NOT removed prior to processing</pre></div>
