Chirpin’ Tavern’s Coupon Promotion

To augment the growth of a restaurant’s business, its owner began selling coupons on a New York City deals website. However, the owner wondered whether selling these steeply discounted coupons was a sound business decision. In this case, students are presented with a spreadsheet with 34 months of sales data and are asked to develop a regression model of sales as a function of key variables. This case is accompanied by a Solutions note that details the steps in developing a model of sales as a function of seasonality, a time trend, and current and past promotional activity.
