and explain their implications for the OLS estimators.
(b) Briefly discuss the alternative
tests, at least two in case, employed to detect the problems of
autocorrelation and heteroscedasticity in the estimated regression
model.

Demand function for Greek yogurt is assumed to be: QGY
= B0 + B1 * PGY +
B2 * PNGY + E
QGY : demand quantity of Greek yogurt.
PGY: price of Greek yogurt. PNGY: price of
Non-Greek yogurt.
(1) What signs do you expect on B1 and B2?
Why
B0, B1, B2 are estimated as
follows:
^B0 = −20.05 with standard error
se^B0 = 36.97. ^B1 = −19.50 with
standard error se^B1 = 1.35. ^B2 =
7.56 with standard...
