What are the conditions and assumptions (or rules of thumb, or whatever you refer to them as) for a Linear Regression t-test. I only have three (1. SRS, 2. for any value of x the y values form a normal regression, 3. The response has a straight line relationship) and I am under the impression that there are more. Also, I'm not sure how to prove that number 2 is true.

Thanks,

Kathy
