Notes:
In this paper, a number of equations based on the sparse-density principle [Verwer, Krabbendam & Kroon (1991). Acta Cryst. A47, 143–144] are given. The corresponding joint probability distributions (j.p.d.'s) are derived, both with the assumption of independent atoms and without. It is concluded that the sparse-density principle is equivalent to the assumption of independent atoms, which leads to the neglect of n-atom interactions for which r1 ± r2 ± … ± rn ≡ 0 (mod 1), which would influence the nth-order moments that appear in the j.p.d.
