Homework Help: Multiple Linear Regression (2 factors, 1 output)

  1. Jul 18, 2010 #1
    Hello all;

    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 form Y = 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!
