چکیده
A single and self-contained method for determining the crystallite-size distribution and shape from experimental x-ray line profile data is presented. We have shown that the crystallite-size distribution can be determined without assuming a functional form for the size distribution, determining instead the size distribution with the least assumptions by applying the Bayesian/MaxEnt method. The Bayesian/MaxEnt method is tested using both simulated and experimental CeO 2 data. The results demonstrate that the proposed method can determine size distributions, while making the least number of assumptions.

In default of prior probability the parameter is not defined as a random variable, hence there can be no genuine prior-free parametric inference. Nevertheless prior-free predic-tive inference regarding any future data is generated directly from the datum of a location measurement. Such inference turns out as if obtained from a certain pdf (" fiducial ") indirectly associated with the parameter....
متن کاملBayesian Analysis of Ceria Nanoparticles from Line Profile Data
A Bayesian/Maximum entropy (MaxEnt) method is applied to quantify the broadening of Xray line profiles in terms of the nanocrystallite size effects in ceria. The analysis is in general agreement with transmission electron microscopy results, while demonstrating the importance of appropriate a priori information needed in the method. The analysis also identifies other microstructural effects, su...
متن کاملsFit: a method for background subtraction in maximum likelihood fit
This paper presents a statistical method to subtract background in maximum likelihood fit, without relying on any separate sideband or simulation for background modeling. The method, called sFit, is an extension to the sPlot technique originally developed to reconstruct true distribution for each date component. The sWeights defined for the sPlot technique allow to construct a modified likeliho...

We describe a Bayesian methodology to evaluate the consistency between the reported Ginga and BATSE detections of absorption features in gamma ray burst spectra. Currently no features have been detected by BATSE, but this methodology will still be applicable if and when such features are discovered. The Bayesian methodology permits the comparison of hypotheses regarding the two detectors' obser...
