Rae's fragmentation (electoral and parliamentary) vote dimension (F)
Description
This indicator seeks to summarize in one value the level of dispersion or concentration of political power, that is to say, whether or not the seats or votes received are concentrated in a reduced number of political parties. The values of the index vary between 0 and 1, so that a value of zero indicates no fragmentation (all the votes go to a single party), while a value close to one indicates strong electoral fragmentation
Este indicador pretende resumir en un valor el nivel de dispersión o concentración del poder político, es decir y de forma resumida si se encuentra concentrado o no los escaños o votos recibidos en una serie de partidos polítcos. Los valores del índice varían entre 0 y 1, de forma que un valor cero indica no hay ninguna fragmentación ( todos los votos van a un sólo partido), mientras que un valor dercano a uno indica fuerte fragmentación electoral
The formula used for its calculation is as follows:
1-\sum_{i}q_{i}^{2}
for i = 1, 2, \ldots,n
Where q_i are the proportions (as parts per unit) of the number of seats or votes (electoral or parliamentary indicator), of the votes obtained by each candidate.
