We are interested in monitoring incoming space-time events to detect, as early as possible, an emergent space-time cluster. Assume that point process events (xi,yi,ti) are continuously recorded where (xiyii) are the spatial coordinates and i is the occurrence time of the i-th event. At a certain unknown instant π, a relatively small cluster of increased intensity starts to emerge. Its location is also unknown. The aim is to let make an alarm go off as soon as possible after π. The alarm system should also provide an estimate of the cluster location. The alarm system should take into account purely spatial and purely temporal heterogeneity. [ABSTRACT FROM AUTHOR] |
