Refer to the IEEE International Conference on Web Intelligence and IntelligentAgent Technology (2010) study on using the volume of chatter on Twitter.com to forecast movie box ofce revenue, Exercise '11.27Il;I (p. 642). Recall that opening weekend box ofce revenue data (in millions of dollars) were collected for a sample of 24 recent movies. In addition to each movie's tweet rate, i.e., the average number of tweets referring to the movie per hour 1 week prior to the movie's release, the researchers also computed the ratio of positive to negative tweets (called the PN-ratia). a. Give the equation of a rst-order model relating revenue (y) to both tweet rate (:61) and PN-ratio (22). b. Which in the model, part a, represents the change in revenue (y) for every 1-tweet increase in the tweet rate (on), holding PN-ratio (:22) constant? c. Which in the model, part a, represents the change in revenue (y) for every 1unit increase in the PN-ratio (4112), holding tweet rate (m1) constant? d. The following coefcients were reported: R2: .945 and R2: .940. Give a practical interpretation for both R2 and RE. e. Conduct a test of the null hypothesis, Ho: B1 = ,82 = 0. Use a = .05. f. The researchers reported the p-values for testing Ho: l = 0 and Ho: [92 = 0 as both less than .0001. Interpret these results (use a: = .01)
