OLS leads to a closed-form solution. The problems in other metrics such as L1 do not. Furthermore, the statistical theory for OLS is much richer than for other metrics in spite of the fact that OLS leads to difficulties in dealing with 'outliers'.

In estimating a linear relationship using ordinary least squares (OLS), the regression estimates are such that the sums of squares of the residuals are minimised. This method treats all residuals as being as important as others.There may be reasons why the treatment of all residuals in the same way may not be appropriate. One possibility is that there is reason to believe that there is a systematic trend in the size of the error term (residual). One way to compensate for such heteroscedasticity is to give less weight to the residual when the residual is expected to be larger. So, in the regression calculations, rather than minimise the sum of squares of the residuals, what is minimised is their weighted sum of squares.

In the online school K12, you can mark an assignment done after doing the assignment. If you wish to skip it (if there isn't an assessment for it) you can go to the OLS, click courses, click the course you are looking for, then select the circle all the way to the right of the lesson you want to skip or mark done. It is best to complete the lesson and mark the attendance for the lesson. You can skip ahead and take the assessment for the lesson, and if you pass, mark the rest of the lesson as done in that area.
