%X This research hypothesizes that the geocoding process represents a transformation of space from continuous to discrete invalidating the homogeneity assumption of the Poisson point process. Therefore, we propose to adapt the existing methods using the whole spatial database of addresses to calculate the expected value and test the null hypothesis of complete spatial randomness. The results show inconsistency in the ordinary methods when a true random pattern is tested while the proposed method is able to distinguish a random pattern from a non random one. We concluded that the geocoding introduces a bias depending on the field and method used.
