It is shown that three kinetic methods [i) initial-value approach, ii) dielectric approach and iii) method of fluctuations in distribution function] for calculating the space-time correlation function using the Vlasov-Boltzmann equation are equivalent to one another, provided that the effective potential in the kinetic equation is proportional to the direct correlation function. This same condition brings the exact zeroth and second moments of the dynamic structure factor S(Q, ω) obtained by the kinetic method. These moment sum rules are independent of the collision term.
