Talk:D'Hondt method

message: I don't understand how d'hondt system may be applied in open list system. In fact I believe this is not possible.
May anybody review this? Explaining how is that possible or removing the reference to the use in open lists systems.
:I know for a fact that it is possible, because it is used in Finland. Each vote is give to a person who is always on a list. The number of elected candidates in a list is counted as in the closed list system. The people who get elected within a list are the ones who have got the most votes.
:Clarification on the issue of ranking candidates on an open-list:
:The amounts of "personal" (you only vote for a person, not a list) votes for each candidate are first used to determine each candidates ranking on the individual list. The candidate with the highest amount of pvotes gets first place, the candidate with the second highest second place etc. The votes are then distributed as in a closed-list system, using the order established by the personal votes. This procedure is explained in the linked open-list article, which I think is sufficent for the purposes of this article which mainly describes the method of seat distribution.

message: Estonian electoral system is a special case in at least two different ways. Firstly, there is a 5% threshold, but it does not mean that "any list which does not receive that threshold will not have any seats allocated to it, even if it received enough votes to otherwise have been rewarded with a seat". In Estonia, for any candidate, even if appearing on a party list which fails to reach the nationwide threshold, receiving the simple quota in one's electoral district is sufficient for receiving the seat in parliament (in the 1st round of vote counting). It is only in the 2nd (district level) and 3rd round (nationwide, modified d'Hondt method) of vote counting that mandates are awarded only to those candidate lists which have received more than the threshold of 5% of the votes nationally. Secondly, Estonia does not use a "typical d'Hondt system" as the (modified) method is used "only" in the 3rd round of vote counting. However, this does not mean that only very few mandates are allocated according to the d'Hondt system. There are 101 seats in the Estonian parliament and in the past elections the breakdown between the mandates awarded in the 1st, 2nd, and 3rd (" d'Hondt* ") rounds of counting have been the following: in 1992: 17, 24, 60*; in 1995: 15, 34, 52*; in 1999: 11, 44, 46*; and in 2003: 14, 60, 27*.--3 Löwi 16:16, 3 October 2005 (UTC)

message: We have to be careful sayin D'Hondt is less proportional than the Sainte-Laguë method, as there is no standard measure of "disproportionality". This is important to remember when discussing all electoral formulas. D'Hondt is a proportional method, in contrast with say Imperiali methods. - Matthew238 07:40, 6 November 2006 (UTC)
thread_title: Proportionality

message: There is a common standard method in Maths to evaluate the deviation of a serial of values against a reference. See the standard deviation function (stdev) in the Excel worksheet. 
So, instead of using the average value as the reference, one may use the values comming
from a proportional division and compare these "good" values againts the "bad" values of method results. 
So it is possible to measure a quality of a proportional method, in a form accepted anywhere.
BUT, in politics, a electoral method is good if it fits the politics agenda.  
So, the discussion of a good method only using math is too much "theorical" and may be away from the reality. 
The Webster method and its equivalent Saint-Lague method are considered the best ones for the proportionality. I have check it for some 50 values using the modified "standard" deviation (square of differences between a proportional representation (integer numbers) and the exact proportional division (real numbers).
That sentence seems pretty right.

thread_title:  d'Hondt method in Bulgaria 

message: : An important result of the method is that a single popular candidate can "draw with him" a lot of lesser-known party colleagues with few personal votes. Also, if the party colleagues with less support fail to pass the threshold, then the elected candidate also represents the failed candidates. For example, candidate B promises to eliminate the dog tax, but is not elected. Then, the votes gained by B benefit party colleague A, who proposes the elimination of dog tax (although not compelled to do so), which was originally B's promise.
I removed the above text from the article as it was uncited, and without some form of citation to explain it seemed to make no sense whatsover. Where do dog taxes come into this? And d'hondt is used in party list systems which, as far as I know, don't ever use individual candidate thresholds. If someone thinks it actually makes sense and can tidy it up, by all means reinsert it, but right now I have no earthly idea what it is the article was actually trying to say. - Chrism would like to hear from you 02:13, 31 March 2009 (UTC)

thread_title:  Removed text from article 

message: The D'Hont system is equivalent to the following statistical
criterion. If each party is a bin, and the (normalized to sum=1)
number of votes is the probability of a stone to fall in that bin,
then the distribution given by the D'Hont system gives the most
probable distribution of a given number of stones among the bins. For
instance, if there are 2 parties A and B, with 100, and 160 votes
respectively, and 4 seats. The D'Hont system predicts A=1 and B=3
seats. In the bin/stones analogy the probability of falling in bin A
is p(A)=0.38462 and p(B)=0.61538. Then the probability of falling 1
stone in A, and 3 in B is p(1,3)=pA*pB^3*4!/(1!*3!)=0.35853, whereas
for instance the probability of falling 2 in A and 2 in B is
p(2,2)=pA^2*pB^2*4!/(2!*2!)=0.33612. So that it is more likely to fall
3 stones in B an 1 in A, than falling 2 in A and 2 in B. In the same
way the other possibilities can be computed (A=0 B=4, A=3 B=1,...) and
the more likely is A=1, B=3. I can't give a mathematical demonstration
for this, but I wrote some Octave programs and tested on a huge number
of cases and in it was verified in all cases. I wonder if it is a
known fact. I know original research material is not suitable to
Wikipedia, but perhaps it is a well known property and someone can
point to a reference. Mariostorti (talk) 15:46, 27 September 2009 (UTC)

message: I'm going to wait a few days for objections first, but I'm liable to remove the paragraph on "government formation", seeing as how the process of government formation in parliamentary systems is entirely independent of the voting system.  (If you wanted an relevant "government formation" aspect of d'Hondt, you could describe the assignement of ministry positions in the Northern Ireland agreement.  That's not at all what the paragraph in the article refers to, though.)  —Preceding unsigned comment added by 150.108.157.180 (talk) 17:44, 4 May 2010 (UTC)

thread_title:  D'Hondt and Jefferson 

message: I'm wondering whether Denmark should figure on both the list of countries using the D'Hondt method and the Sainte-Laguë method. Denmark uses both D'Hondt (135 seats) and Sainte-Laguë (40 seats) to (s)elect the 175 Danish members of the Folketing as documented by the link to the of the description of the Danish electoral system by the Danish Ministry of Economic Affairs and the Interior (note: As portfolios are often divided and combined, the relevant bit is the Interior, whose civil servants are responsible the organisation of all elections in Denmark, though of course aided by municipal civil servants "on the ground"). I've posted this issue on the talkpage of the Sainte-Laguë method as well (section: "Denmark, D'Hondt and Sainte-Laguë - see the article on D'Hondt"), but prefer any comments/discussions/pro et contra to be posted here so as to keep it simple.

message: The initial description of the d'Hondt calculation is correct, stating, "s is the number of seats that party has been allocated so far, initially 0 for all parties."
But then continues, "The total votes cast for each party in the electoral district is divided, first by 1, then by 2, then 3."  The Example grid that follows then uses this method, where ALL parties' vote totals are divided by the same divisor each round.
In d'Hondt, the divisor is only incremented for the winner of each round.
Ref: http://www.europarl.europa.eu/thinktank/en/document.html?reference=EPRS_BRI(2016)580901
The older example on this talk page, with 9 seats and 5 parties, is a correct example.
When the correct d'Hondt method is applied to the current example, the same results are achieved, so this could be an alternate way of making the same calculation, but it's not d'Hondt and definitely does not agree with the equation at the top of the section.

thread_title:  Allocation Example is NOT using d'Hondt 

message: This passage would seem to contradict itself:
The D'Hondt method minimizes the number of votes that need to be left aside so that the remaining votes are represented exactly proportionally. Only the D'Hondt method (and methods equivalent to it) minimizes this disproportionality. Empirical studies based on other, more popular concepts of disproportionality show that the D'Hondt method is one of the least proportional among the proportional representation methods.
Does D'Hondt minimize disproportionality—or not?  -- Calion | Talk 14:07, 6 July 2022 (UTC)
