title: SPSS and ordinary least squares
body: <p>I am doing regression and I am using <a href="http://en.wikipedia.org/wiki/SPSS" rel="nofollow noreferrer">SPSS/PASW</a>. But it doesn't seem to support Ordinary Least Squares, it only has Partial least Squares and 2-stages Least Squares. Any suggestions about what to do?</p>
