| Jun 5, 2014 at 21:25 | comment | added | jtolle | @whuber, I tried to answer your question with an edit to my own. Basically, my new observations would be meant to test a hypothesis that another variable affects y. I phased this as a new variable q, but it could also be one of my xs at a values outside the range it's been seen historically. I know that in order to design any experiment that I need to know or assume something about the random variation that will be present. What I'm wondering is how my regression results help me fill in the necessary assumptions. Thanks. | |

added constant term to regression equation
