 You can see that even with just two continuous variables, coming up with good visualisations are hard. But that's reasonable: you shouldn't expect it will be easy to understand how three or more variables simultaneously interact! But again, we're saved a little because we're using models for exploration, and you can gradually build up your model over time. The model doesn't have to be perfect, it just has to help you reveal a little more about your data.
 
-I spent some time looking at the residuals to see if I could figure if `mod2` did `mod1`. I think it does, but it's pretty subtle. You'll have a chance to work on it in the exercises.
