%X scan statistic has been generally used to identify spatial clusters derived from adverse phenomena, as well as from epidemiological studies. poisson and space-time permutation models are appropriate for counting data, where the null hypothesis assumes randomness in a space-time distribution of a phenomenon. in space-time studies randomness is seen as the same occurrence risk in every location, regarding (expected) time period. for analysis purposes, it was considered homicide data occurred in the jo£¿o pessoa city, para¨ªba state, brazil, by stabbing between 2001 and 2009. from these data, possible patterns in homicide occurrence were investigated and therefore, space-time behavior of the phenomenon was analyzed, identifying high risk areas. after comparing maps using an epidemiological approach, it was verified that scan statistic using poisson model, featuring 7% of the population restriction, had the best results. the model identified the presence of frequent clusters (recidivist clusters) over the years in the northern and western regions of the city.
