Question: In the linear model E(yi) = ????0 + ????1xi, consider the fitted line that minimizes the sum of squared perpendicular distances from the points to

In the linear model E(yi) = ????0 + ????1xi, consider the fitted line that minimizes the sum of squared perpendicular distances from the points to the line. Is this fit invariant to the units of measurement of either variable? Show that such invariance is a property of the usual least squares fit.
