The variance of electron-density maps (observed, difference and hybrid) is estimated in P1 under the hypothesis that the phases are distributed about the correct values according to von Mises distributions.
research papers
A new set of statistical formulas estimating the σA parameter are described and their mean features are studied.
research papers
The variance in any point of the electron-density map is estimated for any space group, whether centric or acentric. Calculations may be performed no matter how poor the structure model.
research papers
The method of joint probability distribution functions has been applied to formulate a probabilistic analysis of the hybrid Fourier syntheses.
