Explain Least Squares Regression Estimating σ²?
In the process of least squares, the sum
of residuals must be equal to zero.
True
False
Suppose the (X,Y) pairs are: (1,5), (2, 3), (3, 4), (4,2), (5,3), (6, 1).
Would the least squares fit to these data be much different from the least squares fit to the same data with the first
pair replaced by (1,15)? Briefly explain.
