Item _refine_ls_shell.wR_factor_R_work
Description
Weighted residual factor wR for reflections that satisfy the
resolution limits established by _refine_ls_shell.d_res_high
and _refine_ls_shell.d_res_low and the observation limit
established by _reflns.observed_criterion, and that were used
as the working reflections (i.e. were included in the
refinement) when the refinement included the calculation of
a 'free' R factor. Details of how reflections were assigned
to the working and test sets are given in _reflns.R_free_details.
( sum|w |Y~obs~ - Y~calc~|^2^| )^1/2^
wR = ( ---------------------------- )
( sum|w Y~obs~^2^| )
Y~obs~ = the observed amplitude specified by
_refine.ls_structure_factor_coef
Y~calc~ = the calculated amplitude specified by
_refine.ls_structure_factor_coef
w = the least-squares weight
sum is taken over the specified reflections
