SPSS white papers

[Matthew Pirritano]

Greetings,

I am trying to download a white paper from the SPSS website. I get to the screen that gives me high and low resolution options to download. I click on them and I get an error that internet explorer cannot display the webpage. I've tried to right click and save target as and I get an error as well.

What am I doing wrong?

Thanks
Mat

You don't want x3**2 without x3 also. And, depending on the range of x3,
x3**2 can be highly correlated with X3**2 so you may want to center X3
(X3 - mean(X3)) first.

Y = b0 + b18x1 + b2*x2 +b3*(X3-mean(X3)) + b4*(X3 - mean(X3))**2

can someone plz tell me how to do multiple regression where one of my
indep
variables is related to y in a quadratic way. so my regn equation would
be
