Question 1: a. Consider the following two estimated model: Model 1: Model 2 : Is it true that âo = and ₁ do b. Show that and a₁ = ? Why or why not? where y = Bo + B₁x x = do +ân Σ(x₂-x) = 0 i=1 where is the sample mean. For the simple linear regression model, show that SSTotal = SSRegression + SSError SSTotal = SSRegression Σ(yi - y)² i=1 n Σ(; - y)2 i=1 n Σ(yi - Yi)² i=1 ĝi = Bo + ₁x SSError = Question 1: a.
