The elliptic flow $$(v_2)$$ event-by-event fluctuations in PbPb collisions at 5.02 TeV are analyzed within the HYDJET + + model. Using the multiparticle, so-called $$\textit{Q}$$-cumulant method, $$v_2$${2}, $$v_2$${4}, $$v_2$${6}, and $$v_2$${8} are calculated and used to study their ratios and to construct skewness $$(γ^{\text{exp}}_1)$$ as a measure of the asymmetry of the elliptic flow distribution. Additionally, in order to check if there is a hydrodynamics nature in the elliptic collectivity generated by the HYDJET + + model, the ratio of $$v_2$${6} – $$v_2$${8} and $$v_2$${4}– $$v_2$${6} distributions is calculated. The analysis is performed as a function of the collision centrality. In order to check the HYDJET + + model responses, the results of this analysis are compared to the corresponding experimental measurements from the ALICE, ATLAS, and CMS experiments. A rather good qualitative agreement is found.
