After long time I here again to ask for your help, which is great always...
I want to run regression that the dependent variable is ROA4 while the Lnsalesgro, lnsales, RDAssets, LTSTassets are the independent variables. The procedure is as follow:
proc reg data=sasuser.sasfile010916;
model roa4 = Lnsalesgro lnsales RDAssets LTSTassets;
How should I write it if I want that ROA4 will be always from t-1 (the year before). It means, for example, that the ROA4 will be taken from 2003 while the Lnsalesgro lnsales RDAssets LTSTassets from 2004?
Thanks for any help,
