Solved When Minimizing The Sum Of Squared Errors Chegg Ordinary least squares regression is defined as minimizing the sum of squared errors. so after doing this regression (ols) then what is the purpose of optimizing sse (or mse, rmse etc.) if linear regression already revolves around optimizing the position of the best fit line that minimizes the sum of squared errors?. If you expand this sum, you get $$ n \hat \beta 0 \sum {i=1}^n y i \hat \beta 1 \sum {i=1}^n x i.$$ the terms $\sum y i$ and $\sum x i$ are fixed constants that do not depend on the coefficients. so if i want this sum of errors to equal zero, there are two free variables for this single equation, and there are in general infinitely many solutions as a result. Lastly, there is the case of e1 = 0.5 and e2 = 0.2. e1 is further away to start, but when you square it 0.25 is compared with 0.4. anyway, just wondering why we do sum of squares erie minimization rather than absolute value. 0.52 = 0.25> 0.04 =0.22 0.5 2 = 0.25> 0.04 = 0.2 2 monotonic transformations preserve order. Rule 1: the power rule. example: \[\begin{align*} f(x) &= x^{6} \\ f'(x) &= 6*x^{6 1} \\ &=6x^{5} \end{align*}\] a second example can be plotted in r.the function is.
