The functions Θ_n(M), n = 1, 2, 3 for Monte-Carlo events in the scenario of uniform distribution (upper panels). The remaining panels show clustering λ = 1∕3 (middle panels) and anti-clustering scenarios λ = 1∕20 (lower panels). Each multiplicity bin is generated by N_M = 6000 events. The red lines correspond to the expected dependence for uniform distribution, Θ _n (M) = 1 (Eq. (34)).
