State if the following is True or false and provide a brief explanation for your answer. Consider Population model Y = Bo + B1X1+ B2X2+ B3X3 + µ. Now consider the following statements a to c. Assumption MLR 1 – 4 is satisfied if and only if: a. X,has no effect on Y after X, & X, have been controlled for which means B3 = 0 b. X3 may or maynot be correlated with X, & X, . All that matters is that X, & X, are controlled for X,has no effect on Y. c. Given that B3 = 0 we are inclined to estimate the equation to include X2. Serial correlation (also called Autocorrelation) is where error terms in a time series transfer from one period to the same period.

State if the following is True or false and provide a brief explanation for your answer. Consider Population modelY = Bo+ B1X1+ B2X2 + B3X3 +µ. Now consider the following statements a to c. Assumption MLR 1– 4 is satisfied if and only if: a. X,has no effect on Y after X, & X, have been controlled for which means B3 = 0 %3D b. X3 may or maynot be correlated with X, & X2 . All that matters is that X, & X, are controlled for X,has no effect on Y. c. Given that B3 = 0 we are inclined to estimate the equation to include X3. Serial correlation (also called Autocorrelation) is where error terms in a time series transfer from one period to the same period.
