Each observation $${\displaystyle i}$$ includes a scalar response Pogledajte više In the previous section the least squares estimator $${\displaystyle {\hat {\beta }}}$$ was obtained as a value that minimizes the sum of squared residuals of the model. However it is also possible to derive the same estimator from other approaches.
