A new statistical test for distinguishing between centrosymmetric and non-centrosymmetric structures
G. N. Ramachandran, R. Srinivasan · Acta Crystallographica · 1959
Some new statistical tests for distinguishing between centrosymmetric and non-centrosymmetric structures are described. The tests are based on the possibility of generation of a random set of intensities from the data available for a given crystal such as to afford a pair of independent variables. The probability distributions and other statistical parameters connected with such a pair are given and are also illustrated on practical cases.
