Applyng Shannon Entropy to Analise Violence Against Women by Departments in Peru

摘要

Violence against women in Peru is a topic that is becoming increasingly more visible, facing this reality and the climate of impunity. This article presents a map of information on the departments with the highest rate of violence against women, on a scale of colors. To reach this result, the entropy-weight method was used, which is based on Shannon entropy theory, in order to obtain a ranking. The entropy-weight method was applied to calculate the weights of the criteria; and then, the departments studied were classified according to the results of a weighted sum. The selection criteria that were taken into account in this study were percentage of physical violence against women (C1), percentage of sexual violence against women (C2), percentage of psychological or verbal violence against women (C3), percentage of women who suffered violence and sought help (C4), reported cases of family or sexual violence (C5), the index of gender inequality in the labor force indicator (C6), and cases of victims of femicide (C7). The results shown that the departments that presented higher violence against women were Madre de Dios, Moquegua, Tacna, Tumbes, and Ayacucho.
