Vicki is in charge of the operations of Lyber, a ride-sharing start-up based in London. In order to understand what influences the demand Lyber faces, she asked Alan, her intern analyst, to conduct a regression analysis. The data Alan pulled out from the company's database is summarized in Table 3.1. The data includes the number of rides its customers requested (in the unit of 1,000 rides) in a day, the high temperature of the day (in Celsius), the price Lyber charges (pound per kilometre, /km), and whether the date recorded falls in a weekend or not (1 if weekend, 0 if not). The output of the first regression that Alan ran is exhibited in Table 3.2.
