The weighted mean m is
| ![\begin{displaymath}
m \eq
{\sum_{i=1}^N \ w_i^2 d_i \over
\sum_{i=1}^N \ w_i^2
}\end{displaymath}](img22.gif) |

where wi2>0 is the squared weighting function.
This is the solution to the
fitting problem
;in other words,
| ![\begin{displaymath}
0 \eq {d \over dm} \ \sum_{i=1}^N \ [w_i(m - d_i)]^2\end{displaymath}](img24.gif) |
