  The frequency distribution of different parameters of an EXAFS spectrum can
be directly sampled by analysing a population of simulated spectra produced by
adding computer-generated noise to a reference pattern. The procedure gives
statistical estimators of the parameter obtained with different data processing
strategies to test the performance of a strategy, to evaluate the bias
introduced by random noise, and to clarify the amount of information actually
contained in an experimental spectrum. Examples are given for the two simple
local structures of an Ag atom sorrounded by two oxygens or by six iodines.
