Predicting movie revenue: preliminary analysis. The response variable is a movie's total U.S. revenue (USRevenue). Let's consider as explanatory variables the movie's budget (Budget); opening weekend revenue (Opening); the number of theaters (Theaters) in which the movie was shown during the opening weekend; and the movie's IMDb rating (Opinion), which is on a 1 to 10 scale (10 being best). Although this rating is updated continuously, we'll assume that the current rating is the rating at the end of the first week.
(a) Using numerical and graphical summaries, describe the distribution of each explanatory variable. Are there any unusual observations that should be monitored?
(b) Using numerical and graphical summaries, describe the relationship between each pair of explanatory variables.
