CLC calculator

This little web page is a supplement to the paper A continuous rating method for preferential voting, where the so-called CLC rating method is proposed for quantitatively rating the social acceptance of different options which are the matter of a preferential vote. The button below starts a java applet which allows to enter preferential voting data to apply the CLC rating method.

Some hints for entering data

Please, take a look at the examples to see how to enter the data. Here are some additional hints:
ITEMS = ... (required)
- must be followed by the number of items
- after that, one can specify the item labels, preceded by : and separated by blank spaces
- by default, the labels will be a b c ...
SCALE = ... (optional)
- allows to specify the total number (or weight) of voters when some abstention is present
- by default, it is taken to be the total numer (or weight) of actual votes (for FORMAT = 1,2,3) or the maximum turnover (for FORMAT = 0)
PROFILE LENGTH = ... (required for FORMAT = 1,2,3)
- must be followed by the number of lines used to enter the ranking votes
FORMAT = 0
- to directly input a Llull matrix
- the empty diagonal cells are indicated by *
- optionally, each line may start the corresponding item, followed by :
FORMAT = 1,2,3
- to input a profile of rankings
- each line may start by indicating the corresponding number of votes (or weight) followed by :; the default is 1
- in the case of a truncated ranking, absent items are indicated by *
FORMAT = 1
- each ranking is specified by enumeration, like in b > c > a or a > b = e
- blank spaces may be omitted as long as consecutive item labels remain separated
- two item labels being separated only by one or more blank spaces is equivalent to their being separated by =
FORMAT = 2
- each ranking is specified by a list of ranks, like in 3 1 2
- more generally, one can give a list of (positive) rates (the lower the better) from which CLC_computer will extract the corresponding ranking
- so, the following inputs are all equivalent: 1 2 * * 2, 1 2.5 * * 2.5, 7 90 * * 90
FORMAT = 3
- like FORMAT = 2, but larger rates are considered better
#
- this character introduces a comment: the remainder of the line is disregarded
