2a) Let income denote the person's income and age denote the persons age. We would like to run an OLS regression on the equation BMI=B0+B1fast+B2income+B3age+U. Write down all the assumptions that guarantee that the OLS estimators of the coefficients of this equation are unbiased correct answers 1)Linearity- E[U|fast, income, age]=0, The expected value of y is linear in X1,X2,X3 2)Exogeneity- E[U|fast, income, age]=0, unobservables are constant and do not effect BMI 3)Random Sampling- The dat...

Cross Sectional Linear Regression Exam Questions Answered Correctly (Graded A+) 5 Classical Linear Assumptions - Answers Linearity, Random Sampling, no perfect collinearity, zero conditional mean, homoskedasticity 6th Linear Assumption - Answers errors are normally distributed What proves 6th linear assumption - Answers central limit theorem - for large n. Although this is weak as the error distribution depends on the number of factors in u and their individual distribution. Also Assumes all ...

Multiple Regression Analysis- Estimation Chapter 3 Exam Questions and Correct Answers Latest Update 2024 Already Passed why is multiple regression analysis more amenable to ceteris paribus analysis? - Answers You can explicitly control for many other factors that simultaneously affect the dependent variable In a multiple regression how is u related to x1 and x2? - Answers The expected value is 0. For any values of x1 and x2 in the population the average of the unobserved factors is equal to 0...
