(a) Distinguish between autocorrelation and heteroscedasticity 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. (c) Using the data on consumer prices, broad money (M2) and Treasury bill rate, as given in question (1), test the quantity theory of money (QTM) as represented by: pt=β0+β1mt+β1yt+ut such that β0>;β1>0;β2<0;β1=1;β2=-1 Show the estimated regression model, together with all...

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...

A. Assume b0 = 12.953, and b1 = -2.5. For x = 25, predict y. Round to 3 digits. B. if x is increased by 10 units, how much does y-hat change? Round to 3 digits. Use the points to answer the following: x y 12 17 21 15 28 22 8 19 20 24 C. How much correlation is there between x and y? Round to four decimals and use leading zeros if necessary. D. How much of the...
