In this case, the parameter DistC-T indicates the deviation of the analyzed values relative to the most probable
values.
For a correct interpretation of the parameter DistC-T, it is necessary to take into consideration the distance
between the points which form the cluster. Therefore, we propose an index for risk analysis IR, as a function of
the ratio between the parameter DistC-T and the position of target pair of values relative to the position of
centroid, defined as following (4):
