Answers to Midterm Test No. 1 1. Consider a regression model of relating Y (the dependent variable) to X (the independent variable) Yi = (0 + (1Xi+ (i where (i is the stochastic or error term. Suppose that the estimated regression equation is stated as Yi = (0 + (1Xi and ei is the residual error term. A. What is ei and define it precisely. Explain how it is related to (i. ei is the residual error term in the sample regression function and is defined as eI hat = Y

The scenario is the number of Wal-Mart stores for each year from 2003 - 2010. The data is (2003‚ 4906)‚ (2004‚ 5289)‚ (2005‚ 6141)‚ (2006‚ 6779)‚ (2007‚ 7262)‚ (2008‚ 7720)‚ (2009‚ 8416)‚ (2010‚ 8970). Each of these graphs is plotted with these points. With this plot I need to formulate a curve of best fit using the correlation coefficient. This graph is about the number of Walmart employees. The X-axis is the Time ( years after 2002). The Y-axis is the number of Walmart employees (in thousands)
