Detección de fraude con modelos basados en agentes: las elecciones mexicanas de 2006Keywords: mexican elections, agent-based model, electoral fraud, political simulations. Abstract: in this paper an innovative tool is applied for the detection of electoral fraud by analyzing statistical distributions of the official results. with this aim a computational model is developed to describe the dynamics of an electoral campaign that conditions the individuals' political preferences. the agent-based model is built assuming that in a clean process the electoral outcome depends, essentially, on preferences subjected to the influence of social interaction and global information. in contrast, in order to simulate an electoral fraud the model is modified such that the voting behavior of the citizens is manipulated on election-day. the model is calibrated with data form the 2006 mexican electoral campaign for the presidency, and the presence or absence of fraud is validated using the kolmogorov-smirnov test, a non-parametric procedure. with information aggregated at the electoral district level, the simulation model rejects the existence of a large scale fraud where at least 5-6% of the total vote tally is manipulated in favor of a particular candidate.
