Determine the equation of a straight that best fit the points:
Code:X| 0 | 2 | 4 | 6 | 8 | 10 | Y|1.12 |5.06 |9.09 |13.12 |17.14 |21.11 |
Is this:
$\displaystyle \sum_{k=1}^{m} (d_k)^2 = \sum_{k=1}^{m} [f(x_k) - \phi (x_k)]^2 $
$\displaystyle \phi (x) = \alpha_1 g_1(x) + ... + \alpha_n g_n(x)$
$\displaystyle F(\alpha_1 , \alpha_2 , ..., \alpha_n ) = \sum_{k=1}^{m} (d_k)^2 = \sum_{k=1}^{m} [f(x_k) - \phi (x_k)]^2 $
