A new model for statistical error analysis in XAS: about the distribution function of the absorption coefficient

Under some general hypothesis, this paper proposes a theoretical model, showing that a gaussian distribution is generally a good approximation of the experimental distribution of the absorption coefficient. This result is confirmed experimentally by usage of appropriate statistical tests.
