# Non-Linear Relationship for a Log-Log Model

I currently have a log-log model. Its scatter plot looks like this:

I am currently stuck after this. I need to find a non-linear relationship to predict how log (X Variable) will affect log (Y Variable). Would simply using this log-log model be enough to predict? Or would I need to manipulate the model further by adding another term such as a squared log(x variable) term, much like in a quadratic model?

• Welcome to the site. Can you clarify why you would "need to find a non-linear relationship to predict how log (X Variable) will affect log (Y Variable)?" Is this part of a class assignment that specifically asked for it? Apr 16, 2016 at 4:41
• Yes, the class assignment specifically asked for it. Apr 16, 2016 at 4:42
