Fixed the error in section 2.3, exercise 7, where instead of regressing "ptratio" onto "crim", we mistakenly used "nox" onto "crim". Also, instead of using a quadratic term, we used a cubic term.
Previously:
boston_df["ptratio2"] = boston_df.nox**3
This has been corrected to:
boston_df["ptratio2"] = boston_df.ptratio**2
Thanks to @eraunio for bringing this to our attention in discussion #53.
