Question 60016: Dear Sir, Madam,
Please can you help me with the following?
Laura wanted to build a multiple regression model based on advertising expenditures and CoffeeTime’s™ price index. Based on the selection of all normal values, she obtained the following:
1) Multiple R = 0.738
2) R-square = 0.546
By using lagged values she came up with the following:
1) Multiple R = 0.755
2) R-square = 0.570
Explain the differences in using these different models. How could CoffeeTime™ further optimize this model?
I do not need to make a calculation but I need to come up with arguments to explain the differences.
Please can you shed your light on my problem?
Thanks very much,
Claudia Patricia Cardenas
