Problem 1 Given m data points ($1,y1),($2,y2),...,(:r:m,ym). We want to use the least squares method to t a line 3; = c0 + c133 to these data points. Unlike the concrete examples during class, the goal of this problem is to derive a general formula for the least squares solution (g, 61). a/ Set up the least squares problem An: = b. b/ Compute ATA and its inverse (ATA)1. c/ Derive the formula for the least squares solution (60, 81)
