Part each) 2 Write TRUE or FALSE next to each statement. (45 points total, 3 points 1· Consider the multivariable regression model: If there is correlation between Xa and the error term, then only 2 will be biased. 2. The no perfect multicollinearity assumption is required for the OLS estimates of a Both R2 and adjusted R2 (denoted as R2) are always between 0 and 1. The Ordinary Least Squares (OLS) estimation method minimizes the sum of the bivariate regression function to be BLUE 3.- 4. absolute errors. 5. 6. _ 7. In OLS, the sum of the residuals is zero (ie, ,u.-0). _ In bivariate regression, the sample regression function is: Vi = + 1x, We reject the null hypothesis when the p-value is larger than the significance level, a. 8. In bivariate regression, omitted variable bias implies that Elu X 0. 9Excluding the intercept from a regression model will not affect the slope estimates because the intercept reflects an outlier.Explanation / Answer
