R merge = , R r.i.m. = and R p.i.m. = − , where I i(hkl) is the ith intensity measurement, N is the number of observations of reflection hkl, including symmetry-related reflections, and 〈I(hkl)〉 is its average intensity. R r.i.m. (or R meas) and R p.i.m. are improved multiplicity-weighted indicators of the quality of the data, the redundancy-independent merging R factor and the precision-indicating merging R factor, the latter computed after averaging multiple measurements (Weiss, 2001 ▶; Evans, 2006 ▶).
