Glitz Analytics has created a regression model to predict the weekly box office revenue of Broadway shows. The idea is to predict next week's box office revenue for a show based on the current week's box office revenue of the show and also based on whether the next week is a holiday week or not. The 4 holiday weeks in a year are Easter week, Independence Day week, Thanksgiving week and Christmas week. The specific definitions of the variables used in the model are:

REV1 = the box office revenue ($) of the show in the next week

REV0 = the box office revenue ($) of the show in the current week

HOL1 = 1, If next week is a holiday week 0, If next week is not a holiday week
