Multiple Regression - Dummy variables - 15.37 - RestaurantRatings 

Thanks a lot Jason! Great illustration! Really helpful!

Hi Jason, What if you are working with two categorical independent variables and a continuous dependent variable? For example: restaurant type and neighborhood as predictor of score. How can you predict a score for each combination of type/neighborhood? I saw your post on interactions but that was the interaction between a categorical and continuous independent variable,right? It seems like that approach would not work with two categorical independents...
