Wal-Mart is the second largest retailer in the world. The data file (Wal-Mart Revenue 2003-2008.xlsx) is posted below the case study two file, and it holds monthly data on Wal-Mart’s revenue, along with several possibly related economic variables.

  • Develop a multiple linear regression model to predict Wal-Mart revenue, using CPI, Personal Consumption, and Retail Sales Index as the independent variables.
  • Find the residuals and the predicted values for the multiple regression model, and then plot the residuals against the predicted values by Excel’s scatter chart (Insert tab > Charts > Scatter chart). Comment on what you see on the plot.
  • Does it seem that Wal-Mart’s revenue is closely related to the general state of the economy? Explain it.
