2. Correlation of error terms 
3. Non-Constant variance of error terms 
4. Outliers 
5. High-leverage points 
6. Collinearity 
How to check for linearity - 1. Check the scatterplot of Y vs. X variable. Is it linear? 
2. OR residual plot vs. fitted plot (especially useful in multiple regression). We want to see no 
patterns in this plot

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...
