multiple responses in PLS

Jonison — Mon, 08 Jul 2019 14:20:33 GMT

Hello, all, I am using PLS node, but seems it only allows one target (Y response). My model have multiple targets to predict, can this be done using PLS node in SAS miner or I have to look for other approach?

Thanks,

As far as I know, Enterprise Miner allows only a single Y in Partial Least Squares.

You could use PROC PLS in base SAS, which can handle multiple Y; and you can even create a "code node" in Enterprise Miner which calls this PROC PLS code. But I think the subsequent problem would be that all of the model evaluation tools in Enterprise Miner expect a single Y variable (actually, I'm not 100% sure about this, but I have never seen Enterprise Miner examples with more than one Y variable).

Thanks, I suspect the PLS in enterprise miner would only accept one Y variable.

I will try your adviced SAS codes or using R to do the job.
