sas里可以作，具体命令要看帮助（Help->using this window->搜索proc pls->Overview）。

语法如下：

The following statements are available in PROC PLS. Items within the brackets < > are optional.

PROC PLS < options > ;

BY variables ;

CLASS variables < / option > ;

MODEL dependent-variables = effects < / options > ;

OUTPUT OUT= SAS-data-set < options > ;

To analyze a data set, you must use the PROC PLS and MODEL statements. You can use the other statements as needed.
