spps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.
