I am reading a text book published in 94 and it mentioned a procedure called REG for regression. Unfortenately it seems that REG is no longer used in SAS9.0. My question is what is the equivalent procedure in doing regression analysis in SAS9?
PROC REG remains available in SAS 9 to customers who have licensed SAS/STAT software. If you're not finding it, that suggests that your site no longer licenses it, or it was not installed. You should check with whoever installs/manages SAS at your site.
