Predicting with interactions
As with every other regression model you've created, the fun part is making predictions. Fortunately, the code flow for this case is the same as the one without interactions — statsmodels can handle calculating the interactions without any extra prompting from you. The only thing you need to remember is the trick for getting combinations of explanatory variables.
mdl_price_vs_both_inter is available as a fitted model, itertools.product is loaded.
