Statistical descriptors

Overview

Statistics and statistical techniques are used extensively in crystallography. A separate online document Statistical Descriptors in Crystallography prepared for the International Union of Crystallography provides an authoratitive statement of the use of statistics in crystallography. The document contains a glossary of statistical terms and sections on the following topics:

• Glossary
• Basic notions
• Uncertainty of measurement
• Refinement
• Refinement on I, |F|² or |F|?
• Defects in the model
• Weighting schemes
• Recommendations
