answers
Which of the following statements are accurate about the population regression
model?
(a) ui is the stochastic component of Y i .
(b) α^+β^Xi is the systematic component of Yi .
(c) Both (a) and (b) are correct.
(d) Neither (a) nor (b) are correct. - ✔✔(c) Both (a) and (b) are correct.
Which of the following statements are accurate?
(a) u^i is an estimate of ui .
(b) Xi is assumed to be measured without error.
(c) Both (a) and (b) are correct.
(d) Neither (a) nor (b) are correct. - ✔✔(c) Both (a) and (b) are correct
Which of the following statements are accurate?
(a)E(ui)=0.
(b) E(u2i )=0.
(c) Both (a) and (b) are correct.
(d) Neither (a) nor (b) are correct - ✔✔(a) E(ui)=0.
, Which of the statements are accurate?
(a) By specifying a bivariate regression model we are assuming that the impact of
a one unit increase in Xi will always be β .
(b) By specifying a bivariate regression model we are assuming that there are no
other variables that cause Y i (c) Both (a) and (b) are correct.
(d) Neither (a) nor (b) are correct. - ✔✔(c) Both (a) and (b) are correct.
Which of the following statements are accurate?
(a) In order to estimate a bivariate regression model, you must have at least two
cases.
(b) If Xi=4 for all observed Xi you can estimate a bivariate regression model.
(c) Both (a) and (b) are correct.
(d) Neither (a) nor (b) are correct. - ✔✔(d) Neither (a) nor (b) are correct
Which of the following statements are accurate?
(a) In hypothesis testing from a bivariate regression model, our conclusions do not
depend on whether or not we have a directional hypothesis.
(b) The null hypothesis for any hypothesis test about β will be that β=0 .
(c) Both (a) and (b) are correct.
(d) Neither (a) nor (b) are correct. - ✔✔(d) Neither (a) nor (b) are correct.
In this example, if an individual has judged that Iraq war is a complete failure,
meaning that they have a value of 0 for the independent variable, what would be
their expected value for "Blair Feelings?"
