View source: R/GallagherModInv.R

Calculates a modified Gallagher index (inverted).

1 | ```
GallagherModInv(Z,R)
``` |

`Z` |
Population vector |

`R` |
Vector for the representatives |

The representation score is calculated as: 1 - sqrt(sum((Z.mod-R.mod)^2)/2), where Z.mod is Z/sum(Zi^2)^.5, and R.mod is R/sum(Ri^2)^.5
