Weband one variable. The OLS Exercise Sheets asks you to show the general OLS formula is equivalent to the OLS formula in the simple linear regression. OLS may be viewed as the ‘line of best t’ to a set of data points. The closer x0 i is to y i across i= f1;::;ngthe smaller is SSR( ). In essence OLS chooses to make x0 i as close as possible to ...
