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 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 (gamma(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.
