Continue with Problem 8.14. Is there multicollinearity in the previous problem? How do you know? Problem 8.14 You are given the annual data in Table 8-5 for the United States for the period 1971 to 1986. Consider the following aggregate demand function for passenger cars: InYi = B1 + B2InX2t + B3InX3t + B4InX4t + B5InX5t + B6InX6t + ut where In = the natural log DEMAND FOR NEW PASSENGER CARS IN THE UNITED STATES, 1971 TO 1986
Regress Y against X1, X2, and X3 with the following sample data: a. What is the regression...... c.... Does the comparison prove multicollinearity in the data? What is your suggestion for getting rid of the multicollinearity? d. Looking at the results of the original regression only, could you have...
Table 8-7 on the textbook\'s Web site gives data on imports, GDP, and the Consumer Price Index...... c.... in the data? d. Suppose there is multicollinearity in the data but (2 and 3 are individually significant at the 5% level and the overall F test is also significant. In this case, should we...
Continue with Problem C.14, but now assume that X and y are positively correlated with a correlation coefficient of 0.6. Problem C.14 If X ~ N(10, 3) and Y ~ N(15, 8), and if X and Y are independent, what is the probability distribution of a. X + Y b. X - Y c. 3X d. 4X +...
A shipping box is to be reinforced with steel bands in all three directions, as shown in the figure. A total of 150 inches of steel tape is to be used, with 6 inches of waste because of a 2-inch overlap in each direction. Find the dimensions of the box with maximum volume that can be taped as...

If there is collinearity in Problem 8.14, estimate the various auxiliary regressions and find out which of the X variables are highly collinear.Problem 8.14You are given the annual data in Table 8-5 for the United States for the period 1971 to 1986. Consider the following aggregate demand function...
It is proposed that the exhaust gas from a diesel powered electric generation plant be used to generate steam in a shell-and-tube heat exchanger with one shell and one tube pass. The steel tubes have a thermal conductivity of 40 W/m ? K. an inner diameter of 50 mm, and a wall thickness of 4 mm....
