Cluster detection with a modified version of the BYM model (MALES, lung cancer mortality in the province of Lecce, 1992–2001). On the left the first ten steps of sequential cluster detection algorithm were reported: the vertical solid line corresponds to the turning point of DIC score sequence. On the right, detected clusters were highlighted. The initial set Δ was defined as the set of all circular neighbourhoods using 10% of total expected counts to define the maximum circle size.
