1. The problem statement, all variables and given/known data Well I have conducted a regression analysis, and have plotted a graph of my residuals vs my input variable. I know that for a linear regression the residuals must be randomly scattered blahblah, but from this graph, it looks like it has a curve to it ? is this because I only have 10 points, or is it not linear? If it is not linear, where do I go from there? 2. Relevant equations 3. The attempt at a solution Assuming it is not linear, I tried to do the log to the base ten of my output, and ended up with a slightly smaller value of R squared. I also tested with cubic and quadratics, they seem to have a larger value of R squared.
