Tīmeklis2016. gada 7. janv. · $$\mathbf{1}^{\prime} \mathbf{e} = 0 \implies \sum_{i=1}^n e_i = 0$$ In the two-variable problem this is even simpler to see, as minimizing the sum of squared residuals brings us to $$\sum_{i=1}^n \left(y_i - a - b x_i \right) = 0$$ when we take the derivative with respect to the intercept. From this then we proceed to obtain … TīmeklisMathematics. A sum of money is lent out at compound interest for two years at 20% p.a., C.I. being reckoned yearly.
