摘要：

This paper describes some of the deflation problems in multiblock PLS. Deflation of X using block scores leads to inferior prediction of Y. Deflation of X using super scores gives the same predictions as standard PLS with all variables in one large X-block, but the information of the separate blocks gets mixed up owing to the deflation of X. If Y is deflated using the super score instead, these problems disappear. Copyright (C) 2001 John Wiley & Sons, Ltd.
