ABSTRACT

Statistical monitoring is crucial in various domains like biosurveillance, data stream analysis, and manufacturing. This study introduces two novel monitoring procedures by integrating convex hulls with control charting techniques. The first technique focuses on monitoring simultaneously the number and the spatial distribution of events οn a plane under the assumption of a homogeneous Poisson process. Meanwhile, the second procedure introduces a non-parametric monitoring process that aims to detect changes in multivariate data streams. These procedures underscore the significance of geometric-centric monitoring techniques in tackling various challenges across different fields.
