The sensitivity and the specificity of a compound test depend on the distribution underlying the phenomenon. In this paper we consider count distributions unified under Panjer recursive formula and belonging to the Morris family, which verifies useful properties. The influence of the tail weight of the count distributions (that varies among infected and uninfected elements), evaluated in terms of the dispersion index, is investigated in the sensitivity and the specificity of the compound test.
