Generation of the correlation and distance matrices
International Tables for Crystallography (2019). Vol. H, Section 3.8.2.5, pp. 326-327 [ doi:10.1107/97809553602060000953 ]
Generation of the correlation and distance matrices 3.8.2.5. Generation of the correlation and distance matrices Using equation (3.8.3) , a correlation matrix is generated in which a set of n patterns is matched with every other to give a symmetric (n × n) correlation matrix [rho] with unit diagonal. The matrix [rho] can ...

Combining the correlation coefficients 3.8.2.3. Combining the correlation coefficients Correlation coefficients are not additive, so it is invalid to average them directly; they need to be transformed into the Fisher Z value to give References International Tables for Crystallography (2019).

Spearman's rank order coefficient 3.8.2.1. Spearman's rank order coefficient Consider two diffraction patterns, i and j, each with n measured points n((x1, y1), , (xn, yn)). These are transformed to ranks R(xk) and R(yk). The Spearman test (Spearman, 1904 ) then gives a correlation coefficient (Press ...
