... Statistics Where there are less than four independent observations of a given bond length, then each individual observation is given explicitly ... and is the ith observation of the bond length in a total sample of n observations. Recent work (Taylor & Kennard, 1983 ... to the weighted mean, where the ith observation is assigned a weight equal to 1/var(di). This is ...

Classification of bonds
Orpen, A. G., Brammer, L., Allen, F. H., Watson, D. G. and Taylor, R.  International Tables for Crystallography (2006). Vol. C, Section 9.6.2.3, p. 813 [ doi:10.1107/97809553602060000622 ]
... crystallographers, and others who may use it; (ii) to permit a meaningful average value to be cited for each bond length. With reference to (ii), it was considered that a sample of bond lengths could be averaged meaningfully if: (a) the sample was unimodally distributed; (b) the sample standard ...

Orpen, A. G., Brammer, L., Allen, F. H., Watson, D. G. and Taylor, R.  International Tables for Crystallography (2006). Vol. C, Section 9.6.2.2, p. 813 [ doi:10.1107/97809553602060000622 ]
Program system 9.6.2.2. Program system All calculations were performed on a University of Bristol VAX 11/750 computer. Programs BIBSER, CONNSER ... Murray-Rust & Raftery, 1985a,b), as locally modified, were used. A stand-alone program was written to implement the selection criteria, whilst a new program (STATS) was used for statistical calculations described ...
