comment How to explain control variables and interaction effects
E.g. for breadths below $\frac{-\beta_1}{\beta_{12}}\approx 11.3$, volume increases with altitude according to the model with interaction - though this may be far outside the range of breadths you're interested in.

comment How to explain control variables and interaction effects
@restats: Even at entry level, as long as you've covered addition & multiplication you should be able to understand the models - else what's the point in fitting them? Plot them out over relevant predictor values & describe what you see.

comment Differences in edition of advanced statistics books
@rolando2: Outright errors are more likely in earlier printings; so you might be safer with the 7th printing of a 2nd edition (or mature errata) than the 1st printing of a 3rd edition. The inclusion of now-deprecated methods (& omission of modern alternatives) is something I think you have to assess for the particular book in question.
