Subject:      Re: arrays and matrices in Proc Reg

Dear All,
 
I want to use Proc Reg to run a regression of Y on X,,Z, and W where
X,Z and W are matrices of variables and observations. For instance,
you may envisage this as X_ij where i refers to teh observation (=
the row in the data) whilst j stands for one variable sin the group
of the Xs. Similar reasoning of course applies to Z and W.
 
With this information in mind, I am wondering how I would present
that with SAS codes. For instance, could I use ARRAYS in SAS and then
enter them in the regression analysis (Proc Reg), or is there any
other way of doing so. If the latter is true may I have your comments
on how to do it, please?
 
Thank you very much indeed for taking the time to consider my
request. I look forward to hearing from you.
 
Yours sincerely
