What the article says around this equation
alongside a goodness-of-fit statistic that compares to the value expected from counting statistics alone. A low is necessary but not sufficient evidence of a correct structure: a wrong space group with enough adjustable parameters can still fit a pattern well, which is why practitioners cross-check refined models against known chemistry, bond-valence sums, and, wherever possible, an independent technique.
