Reference to mysterious models in Exercise 13.6 (p. 238)

[jkruohon]

Exercise 13.6 says to compare coefficient uncertainties between fit_4 and fit_5, models that were supposedly fit in Section 13.7. But I cannot find any such models fit in that section. What am I missing?

Hi, yes, these models are actually in chapter 14. We added in a forward reference to the appropriate section.
