Before starting this problem set you will need to download the data file from the course web site. The data file is entry data for Southwest airlines. The data consist of a cross section of markets to which Southwest is a potential entrant (that is, they already fly to one endpoint in the city pair). The variables are noted in the data file and include whether or not Southwest entered that market, as well as several market variables. (Note that this is real data, but you might get strange results anyway.) Consider the following model.
