Predicting with a parallel slopes model
While seaborn can automatically show you model predictions using sns.regplot(), in order to get those values to program with, you'll need to do the calculations yourself.
Just as with the case of a single explanatory variable, the workflow has two steps: create a DataFrame of explanatory variables, then add a column of predictions.
taiwan_real_estate is available and mdl_price_vs_both is available as a fitted model. seaborn, ols(), matplotlib.pyplot, pandas, and numpy are loaded as their default aliases. This will also be the case for the remainder of the course. In addition, ìtertools.product is available as well.
