R-factor (crystallography)
MEASURE OF THE AGREEMENT BETWEEN A CRYSTALLOGRAPHIC MODEL AND THE EXPERIMENTAL X-RAY DIFFRACTION DATA
R-factor (crystallographic); Rfactor (crystallographic)
In crystallography, the R-factor (sometimes called residual factor or reliability factor or the R-value or RWork) is a measure of the agreement between the crystallographic model and the experimental X-ray diffraction data. In other words, it is a measure of how well the refined structure predicts the observed data.
