The following table was generated from the sample data of 10 college students regarding the number of parking tickets the student receives in a semester, the student's age, and the student's GPA. The dependent variable is the student's GPA, the first independent variable (x1) is the number of parking tickets, and the second independent variable (x2) is the student's age.

Which of the following is true of heteroskedasticity? a) The R-squared statistic is affected by the presence of heteroskedasticity b) Heteroskedasticty causes inconsistency in the Ordinary Least Squares estimators c) The OLS estimators are not the best linear unbiased estimators if heteroskedasticity is present d) It is not possible to obtain F statistics that are robust to heteroskedasticity of an unknown form
You estimated a linear regression model with 3 explanatory variables using a sample of 29 observations. You are asked to test the overall significance of the model.the F-statistics calculated is equal to 2.567 and the F-critical at 5% level is 3.028. The p-value of the test can be expressed as: Select one: O a. P(F(3,25)<=2.567) O b. 1-P(F(3,25)<=2.567) O c. P(F(3,25)<3.028) O d. 1-P(F(3,25)<33.28)
The error term is heteroskedastic if var(uil Xi = x) depends on x. var(uil Xi = x) is constant for i = 1,..., n. Xi is normally distributed. there are no outliers.
When Y is regressed on X, B, > 0, sx+ 0, sy # 0, and the fraction of the variation in Y explained by the least-squares regression of Y on X does not equal 1. In this example, the sum of the squares of the deviations of the actual Y-values from their mean would definitely be greater than the sum of the squares of the deviations of the predicted Y-values from their mean. 1 A) B) true false 4. When Y is regressed on X, the sample slope is negative, sx + 0, sy + 0, and Y; = Y; for every observation. In this example, the sum of the squares of the deviations of the predicted Y-values from their mean would definitely be less than the sum of the squares of the deviations of the actual Y-values from their mean. A) В) true false 3.
