Question 3 In lecture, we stated that the estimate of ß in Weight Least Squares as: BWLS = (XTWX)-1xTWY Derive BW when p = 1. (It should have a form similar to simple linear regression.) Hint: Notice that we can write a weighted average as: Tw Zi=1 Hint: You may need to use weighted analogues of the sums of squares identities that we have used; you should derive (or expand) the following w2 (x - w)-w) i-1 i-1 W

Fitting a Line to Data The method of least squares is a standard approach to the approximate solution of overdeter- mined systems, i.e., sets of equations in which there are more equations than unknowns. The term "least squares" means that the overall solution minimizes the sum of the squares of the errors made in the results of every single equation. In this worksheet you will derive the general for- mula for the slope and y-intercept of a least squares line....
