True or False: Given the necessary assumption: E(u|X) = 0, β ̂ is a random variable with a distribution centered at 0. Given the necessary assumption: E(u|X) =0, β ̂ is a random variable with a distribution centered at β. Adding more independent variables to a model will only increase R2 if they provide meaningful variation. Adj R2 measures the proportion of the variation in the dependent variable that has been explained by the variation in the independent variable. If...
