The present thesis raises an application of the statistical models of Poisson spatial point processes as well as the Cluster models of the Neyman - Scott type. Particularly, it focuses on evaluating the spatial distribution of criminal acts and its relation to some spatial covariates. In this way, it will be possible to orient and/or establish policies related to citizen security of a national and /or local nature. The study area corresponds to the districts of Lima Centro and Residencial, which takes into account the information of georeferenced locations of the criminal events reported by the victims at the end of the year 2013 until the beginning of 2014. The locations of the crimes are represented by points, and the set of these are considered as a spatial point pattern, which represents a realization of a spatial point process underlying the space of study. Statistical modeling is performed through the intensity of points, which can be estimated for any specific location in the study area and are the log-linear models most commonly used to represent their relationship with a set of spatial covariables whose effects can be represented in a set of parameters; these models are known as parametric models of spatial point processes. The summary statistics, also known as first and second order properties of a point process as well as methods based on distance between points, have been applied for the purpose of developing the exploratory analysis and determining: the type of spatial distribution (regular, random or clusters) that follow the criminal acts (point pattern), the distribution of the distance from an arbitrary point to a place of occurrence of a crime and the distance from one criminal act to another, among others. Finally, it is concluded that the spatial distribution of criminal acts in Lima is not homogeneous, there are clustering or aggregation of points, which are translated into areas with a higher incidence of criminal acts and their intensity is related to the location of the district boundaries, the investment destined to the internal order and the population density.
