Question
Suppose that n= 195 I.I.d. observations for (Y, X;) yleld the following regression results:
v= 32.68 + 67.55Xx, SER= 18.63, R = 0.84
(15.7) (12.5)
Another researcher is interested in the same regression, but he makes an error when he enters the data into the regression: He enters each observation twice, so he has 390 observations (with observation 1 entered twice, observation 2 entered
twice, and so forth).
Which of the following eatimated parameters change
result? (Check all that apply)
O A. The estimated intercept and slope.
O B.
The R of the regression.
Yc. The standard error of the regrussion (SER).
YD. The standard errors of the estimated coefficients.
Using the 390 observations, what results will be produced by his regression program?
Ý= 32.68 + 67.55X, SER =.R = 0.84
