calculation

The calculation formula is:

${\displaystyle {\text{Erfolgswert}}={\frac {\text{Mandatsanzahl}}{\text{Stimmenanzahl}}}}$

The success value is a measure of the influence of a vote on the composition of the committee to be elected.

There is also a relative success value :

${\displaystyle {\text{relativer Erfolgswert}}={\frac {\text{Mandatsanteil}}{\text{Stimmenanteil}}}}$

One speaks of success value equality when all relative success values ​​are equal to 1 or differ only minimally from 1. You can minimize the largest difference, the mean difference or the standard deviation for each of the two values ; each of these six objectives requires a different seat allocation process .
