divisor_methods {proporz}

Divisor methods

Description

Functions to directly apply divisor apportionment methods instead of calling proporz() with a method parameter.

Usage

divisor_round(votes, n_seats, quorum = 0)

divisor_floor(votes, n_seats, quorum = 0)

divisor_harmonic(votes, n_seats, quorum = 0)

divisor_geometric(votes, n_seats, quorum = 0)

divisor_ceiling(votes, n_seats, quorum = 0)

Arguments

votes

numeric vector with number of votes for each party

n_seats

total number of seats

quorum

Vote threshold a party must reach. Used as quota of total votes within a district if less than 1 otherwise as number of votes.

Details

Divisor methods are known under different names:

• d'hondt, jefferson, hagenbach-bischoff: use divisor_floor()

• sainte-lague, webster: use divisor_round()

• adams: use divisor_ceiling()

• dean: use divisor_harmonic()

• huntington-hill, hill-huntington: use divisor_geometric()

All divisor functions call highest_averages_method() with a different sequence of divisors.

Value

The number of seats per party as a vector
