A survey is given of some recent calculations of univariate and multivariate probability density functions (pdfs) of structure factors used to interpret crystallographic data. We have found that in the presence of sufficient atomic heterogeneity the frequently used approximation derived from the central limit theorem in the form of Edgeworth or Gram-Charlier series can be quite unreliable, and in these cases the more exact, but lenghier, Fourier calculations must be made.
