gretl: model 1 File Edit Tests Save Graphs Analysis LaTeX Question 5 In your first year microeconomics course you learned about differentiated products. As an econometrics student differentiated products are interesting because they are prime candidates for hedonic price modelling. As mentioned in class, a hedonic price model is a regression model that relates the price of a differentiated product (a residential house in this case) to its characteristics. For this assignment you will construct a simple hedonic model for...
