Consider the following multiple regression models below. DFemme = 1 if the individual is a female, and is zero otherwise; DMale is a binary variable which takes on thevalue one if the individual is male, and is zero otherwise; DMarried is a binary variable which is unity for married individuals and is zero otherwise, and DSingle is (1-DMarried). Regressing weekly earnings (Earn) on a set of explanatory variables, you will experience perfect multicollinearity in the following cases EXCEPT for:$5 X31O Earn;= 1 DFemme + 2 Dmale + .63 DMarried + 54 DSingle +O Earni == 50+1 DFemme + 2 DSingle + 3 X3iO Earn; = 30 +31 DFemme + 2 Dmale +53 X3iO Earn;= 50+1 DMarried +52 DSingle + §3 X3i

From the given information, The variables are, DFemme=1 if the individual is a female0,…

Explain the concept of Linear Regression with Multiple Regressors?
For major league baseball teams, do higher player payrolls mean more gate money? Here are data for each of the American League teams in the year 2002. The variable x denotes the player payroll (in millions of dollars) for the year 2002, and the variable y denotes the mean attendance (in thousands of fans) for the 81 home games that year. The data are plotted in the scatter plot below, as is the least-squares regression line. The equation for this line is y = 11.43 + 0.23x.

We have data from 209 publicly traded companies (circa 2010) indicating sales and compensation information at the firm-level. We are interested in predicting a company's sales based on the CEO's salary. The variable sales; represents firm i's annual sales in millions of dollars. The variable salary; represents the salary of a firm i's CEO in thousands of dollars. We use least-squares to estimate the linear regression sales; = a + ßsalary; + ei and get the following regression results: . regress sales salary Source Model Residual Total sales salary cons SS 337920405 2.3180e+10 2.3518e+10 df 1 207 208 Coef.
