Rsym = ΣhklI(|Ihkl,I − 〈Ihkl〉|))/Σhkl,IIkhl,I, where Ihkl,I is the intensity of an individual reflection, and 〈Ihkl〉 is the mean intensity of that reflection. 

Rcryst = Σhkl(∥Fobshkl| − |Fcalchkl∥)/|Fobshkl|, where |Fobshkl| and |Fcalchkl| are the observed and calculated structure factor amplitudes for reflections used during refinement (working set). 

Rfree is equivalent to Rcryst but calculated with reflections omitted from the refinement process (test set).
