Hello all;(adsbygoogle = window.adsbygoogle || []).push({});

I'm doing work for my job, and I've forgotten my statistics =(.

I first want to know if what I'm trying to do is possible.

I want to create a linear regression of the formY = a * x1 + b * x2 + c.

As you can see, there is space that is grayed out (those tests were not performed). I was originally instructed to run my experiment by holding x1 constant and varying x2, and holding x2 constant and varying x1. (I made a dummy data set to make it easier to analyze).

I'm attempting to find the parameters (a,b, & c) using the trusty formula [tex]\beta = (X'X)^{-1}X'Y[/tex].

Thanks for your help!
