1.The Breusch-Pagan test for heteroskedasticity A. tests for a relationship between the estimated residuals and the independent variables B. tests for a relationship between the squared estimated residuals and the independent variables C. tests for a relationship between the estimated residuals and the dependent variable D. tests for a relationship between the squared estimated residuals and the dependent variable 2. In the presence of heteroskedasticity hypothesis testing is unreliable (T/F) 3. Plotting the residuals (predicted errors) against the independent variables...
Consider the following results of a multiple regression model of dollar price of unleaded gas (dependent variable) and a set of independent variables: price of crude oil, value of S&P500, price U.S. Dollars against Euros, personal disposal income (in million of dollars) : Coefficient t-statistics Intercept 0.5871 68.90 Crude Oil 0.0651 32.89 S&P 500 -0.0020 18.09 Price of $ -0.0415 14.20 PDI 0.0001 17.32 R-Square = 97% What will be forecasted price of unleaded gas if the value of independent...

When two explanatory variables are highly correlated, should you remove one of the correlated explanatory variables to reduce the multicollinearity problem. A. Yes, it will reduce the standard errors on the coefficients and increase the t statistics. B. No, it will not affect the t statistics on the coefficients. C. No, it will cause the coefficient on the remaining variable to be biased. D. Yes, it will improve the fit of the regression model.
1. Identify the formula for predicting an individual's z score on the dependent variable from their z score on the independent variable. a.) (rxy)(zy) b.) (rxy)(zx) c.) zx/zy d.) (zx)(zy) 2. Data from the 1993 World Almanac and Book of Facts were used to predict the life expectancy for men in a country from the life expectancy of women in that country. The resulting regression equation was Yˆ = 9.32 + 0.79(X). Using the regression equation, what would you predict...
2. According to Cohen's (1988) guidelines, an r of -0.56 would be considered a correlation 3. If two variables are correlated people who have low scores on one variable will tend to have low scores on the other variable. 4. Calculating a correlation coefficient is only appropriate when there is a relation between two variables. 5. A correlation value of would indicate that there was no association between the two variables. 6. regression enables one to predict an individual's score...
Previously, you studied linear combinations of independent random variables. What happens if the variables are not independent? A lot of mathematics can be used to prove the following: Let x and y be random variables with means Wy and Wyr variances o2, and y, and population correlation coefficient p (the Greek letter rho). Let a and b be any constants and let w = ax + by for the following formula. Ww=aux + buy 2 = 3202 + b2x2, +...
5) In a regression model developed to estimate cruise vacation prices, two recorded independent variables were: ship Size (sqft) and ship Capacity (number of people). A correlation analysis yielded the following table: Size Capacity Size Capacity 0.88091 a. There is a high positive correlation between ship Size and ship Capacity. b. Each variable is perfectly correlated with itself. c. One of these two variables should be excluded from the regression model to avoid multicollinearity. d. All of the above statements...
1.Which variables are statistically significant at the 5% level? 2.Which variables are statistically significant at the 10% level? 3.Which variables are insignificant? 4.Please present the correlation matrix of the independent variables. 5.Please run the White test for heteroskedasticity, with cross-products AND PRESENT YOUR RESULTS. Please explain whether the test is significant or not. 6.If the White test is significant, please present the heteroskedasticity-consistent White regression results. 7.Can you test this model for autocorrelation? Why of why not? If you do,...
The multiplication of two variables is used as a predictor if the two variables jointly affect the response. True O False Question 7 1 pts Even if the P-value of the F test in a multiple regression model is nearly zero, it is possible that the R of the model is much less than one. OT False Question 8 1 pts in selecting independent variables for a regression model, neither the forward selection method nor the backward elimination method guarantee...
