  Hadronic cross sections are important ingredients in many of the ongoing
research methods in high-energy nuclear physics, and it is always important to
measure and/or calculate the probabilities of different types of reactions. In
heavy-ion transport simulations at a few GeV energies, these hadronic cross
sections are essential and so far mostly the exclusive processes are used,
however, if one interested in total production rates the inclusive cross
sections are also necessary to know. In this paper, we introduce a
statistical-based method, which is able to give good estimates to exclusive and
inclusive cross sections as well in the energy range of a few GeV. The method
and its estimates for not well-known cross sections, will be used in a
Boltzmann-Uehling-Uhlenbeck (BUU) type off-shell transport code to explain
charmonium and bottomonium mass shifts in heavy-ion collisions.
